Can multiple SN74LVC1G07 outputs share one node?

Compatible open-drain outputs may share one pull-up for wired logic. A push-pull HIGH driver must not share the node.

Which packages are listed?

SN74LVC1G07DBVR is SOT23-5 with C075 marking and SN74LVC1G07DCKR is SC70-5 with CV5 marking.

SN74LVC1G07 Open-Drain Buffer/Driver

Q: What logic function does SN74LVC1G07 implement?

It is a non-inverting open-drain buffer. A LOW input pulls Y LOW and a HIGH input releases Y into the high-impedance state.

Q: Does SN74LVC1G07 require an external pull-up?

Yes. The output can sink LOW or release the node but cannot actively drive HIGH.

Q: Can the pull-up voltage differ from VCC?

The recommended output voltage range is 0 V to 5.5 V. System thresholds, current, timing and sequencing must be verified.

Q: What propagation-delay values are listed?

Typical full-range tpd values are 6.4 ns at 1.8 V, 4.5 ns at 2.5 V, 4.2 ns at 3.3 V and 3.7 ns at 5 V under the stated loads.

Q: What does Ioff provide?

Ioff is specified with VCC = 0 V and VI or VO = 5.5 V, with ±10 µA maximum over the full temperature range.

NYFEA SN74LVC1G07 is a single non-inverting buffer and driver with an open-drain output, specified for 1.65 V to 5.5 V VCC operation. Input A and open-drain output Y accept 0 V to 5.5 V, I_off supports partial-power-down applications, and SOT23-5 and SC70-5 package options are listed.

Product scope: A HIGH input turns the output transistor on and pulls Y LOW. A LOW input turns the transistor off and leaves Y in the high-impedance state. An external pull-up resistor is required to create a valid HIGH level; the device does not source output current.

I/O RANGEVI and VO 0 V to 5.5 V

TEMPERATURE-40 °C to +125 °C ambient

Product Overview and Selection Scope

SN74LVC1G07 combines a non-inverting input stage with an open-drain NMOS output. It can pull a shared node LOW but cannot actively drive it HIGH. The specified VCC operating range is 1.65 V to 5.5 V, and both input A and output Y accept 0 V to 5.5 V under the recommended conditions.

Output architecture

When A is LOW, Y is pulled LOW. When A is HIGH, Y becomes high impedance and the external pull-up network establishes the HIGH level.

Wired logic

Multiple compatible open-drain outputs may share one pull-up to implement active-low wired-OR or active-high wired-AND behavior.

Partial power-down

I_off is specified with VCC = 0 V and VI or VO = 5.5 V, limiting current through the powered-down device path.

Package choice

SOT23-5 and SC70-5 share the same pin assignment but have different footprints, markings and thermal impedances.

Selection boundary: The PDF does not specify Schmitt-trigger hysteresis, an internal pull-up, a guaranteed pull-up resistor value, tri-state control independent of A, or end-product qualification. Pull-up voltage, resistance, bus capacitance, LOW-state sink current, rise time and static power are system design responsibilities.

Logic Function, Truth Table and Pin Assignment

The non-inverting logic function is implemented through an open-drain output: A = L produces Y = L, while A = H produces Y = Z. The external pull-up converts Z into a usable HIGH level.

SN74LVC1G07 open-drain buffer symbol and L-L / H-Z truth table — Non-inverting open-drain buffer function. Z means high-impedance OFF-state, not an actively driven HIGH.

Pull-up boundary: Select the pull-up so the worst-case LOW current keeps VOL within the receiver's VIL requirement. The HIGH level and rising edge are created by the external network, not guaranteed by SN74LVC1G07.

AC Switching and Test Conditions

The Rev A.1 PDF lists typical propagation-delay values over the full -40 °C to +125 °C range under the stated resistor and capacitive loads. Pull-up resistance, total node capacitance and receiving threshold additionally determine the actual rising edge in an application.

SN74LVC1G07 propagation-delay load circuit and pull-up timing conditions — Propagation-delay load conditions from the PDF, with an application reminder that the external pull-up controls the released-node rise.

Timing boundary: The PDF provides typical values but no guaranteed maximum propagation delay or bus rise-time limit. Do not infer a guaranteed maximum frequency. Measure the finished node across voltage, capacitance, resistor tolerance and temperature.

Pull-Up Design, Power Integrity and PCB Layout

The following circuits are application-design guidance, not guaranteed reference circuits defined by the product specification. Use the PDF limits and validate the complete pull-up network, receiving threshold, wiring capacitance and power sequence.

SN74LVC1G07 open-drain pull-up resistor, wired logic and RC rise-time guidance — Open-drain design model: the pull-up establishes HIGH, the transistor establishes LOW, and total node capacitance controls the released-node rise.

Design check	First-order relation	Required validation
LOW-state sink current	IOL ≈ (VPU - VOL) / RPU	Keep IOL within the stated VOL test-current conditions and receiver VIL margin.
Released-node rise	τ ≈ RPU × Cnode	Use the receiver threshold and system timing budget; the PDF does not guarantee a bus rise time.
Static LOW power	P ≈ VPU² / RPU	Include resistor dissipation and device sink power at maximum LOW duty cycle.
Shared wired node	Any active pull-down forces LOW	Only compatible open-drain outputs may share the node; never connect a push-pull HIGH driver.

Keep VPU within the output range: recommended VO is 0 V to 5.5 V, independent of the lower VCC used for the input stage.
Do not leave A floating: the PDF requires every unused input to be held at VCC or GND.
Place local bypassing close to the device: use a short VCC-to-GND loop and confirm the board PDN.
Route the shared node compactly: connector, cable, probe and input capacitance all increase Cnode and slow the released edge.
Validate partial power-down: Ioff limits the device path, while the pull-up and other components can still create system back-power routes.

Application Guidance and Design Limitations

The Rev A.1 specification lists Blu-ray players and home theaters, desktop or notebook PCs, digital video cameras, mobile phones, personal navigation devices and portable media players. In these systems, the device can buffer a control signal without inversion, level-interface through an external pull-up within the 5.5 V output limit, or combine compatible open-drain sources. These are use contexts, not end-product approvals.

Blu-ray and Home TheaterCombine active-low status or control lines after selecting the pull-up for sink current and edge rate.

Desktop and Notebook PCsUse for board-level reset, interrupt or status buffering where an open-drain shared node is appropriate.

Digital Video CamerasBuffer low-speed digital control signals while validating pull-up voltage, capacitance and timing.

Mobile PhonesEvaluate compact open-drain control paths with complete standby-current and power-sequencing checks.

Personal Navigation DevicesUse on local status or control nodes after system-level EMC, timing and pull-up validation.

Qualification boundary: The supplied specification does not establish automotive, medical, functional-safety, life-support or fault-tolerant qualification. Validate EMC, ESD protection, pull-up behavior, power sequencing, thermal limits, assembly and environmental performance in the finished product.

SN74LVC1G07 Engineering FAQs

What logic function does SN74LVC1G07 implement?

It is a non-inverting open-drain buffer. A LOW input pulls Y LOW; a HIGH input releases Y into the high-impedance state.

What supply range is recommended?

VCC is specified from 1.65 V to 5.5 V for operation. The PDF separately lists 1.5 V as the minimum data-retention supply; data retention does not establish normal logic operation.

Does SN74LVC1G07 require an external pull-up?

Yes. The open-drain output can pull LOW or release the node; it cannot drive HIGH. Choose the pull-up from the required VOL, sink current, capacitance, rise time and static power.

Can the pull-up voltage differ from VCC?

The recommended output range is 0 V to 5.5 V, so a pull-up within that limit can support system-level voltage translation. Verify receiver thresholds, current, timing and sequencing in the complete circuit.

Can multiple outputs share one node?

Compatible open-drain outputs may share a pull-up for wired logic. Do not connect a push-pull output that may actively drive HIGH to the same node.

What propagation-delay values are listed?

Typical full-range tpd values are 6.4 ns at 1.8 V, 4.5 ns at 2.5 V, 4.2 ns at 3.3 V and 3.7 ns at 5 V under the stated loads. No guaranteed maximum is listed.

What does Ioff provide?

Ioff is specified with VCC = 0 V and VI or VO = 5.5 V, with ±10 µA maximum over the full temperature range. It limits the device path but does not eliminate other board-level back-power routes.

Which package should be selected?

SN74LVC1G07DBVR is SOT23-5 with C075 marking. SN74LVC1G07DCKR is SC70-5 with CV5 marking. Both are MSL 3 and packed 3,000 units per reel.

Can input A be left open?

No. The PDF explicitly requires unused inputs to be held at VCC or GND. Pin 1 is N.C. and should not be used as a functional connection.

Do the listed applications establish product certification?

No. The application list identifies possible use contexts only. Qualification, safety, EMC, reliability and production validation remain system responsibilities.
