74LVC1G34GV-Q100H

Overview

The Nexperia 74LVC1G34GV-Q100H is a single buffer in the SOT753 (SC-74A) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an input voltage up to 5.5 V. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Propagation delay ranges from 0.5 ns to 8.6 ns depending on voltage, with output drive capability of ±24 mA at 3.0 V.

Feature Summary

• Schmitt-trigger action provides tolerance for slow input rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent backflow current.
• Overvoltage tolerant inputs allow direct interfacing with 5 V devices.

Applications

• Mixed 3.3 V and 5 V logic environments
• Partial power-down applications
• Automotive electronics

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74A package configuration required for your design. Confirm that the AEC-Q100 Grade 1 qualification meets your automotive reliability standards. Ensure the operating temperature range aligns with your system's thermal requirements.

Selection Notes

Select this component when a single non-inverting buffer with Schmitt-trigger inputs is needed. It is suitable for translating signals between different voltage domains. Consider the SOT753 package size if space constraints require a compact surface-mount solution.

Part Context

This part belongs to the 74LVC1G34-Q100 family of single buffers. Other variants include the GW package (TSSOP5) and GZ package (XSON5). All share identical electrical characteristics but differ in physical footprint and pinout orientation.

Replacement Considerations

Check for equivalent parts from other manufacturers offering similar voltage levels and package types. Verify pin compatibility before substitution to ensure correct functionality without PCB redesign.

FAQ

What is the function of the IOFF circuitry?

The IOFF circuitry disables the output when the device is powered down, preventing potentially damaging backflow current through the device.

Is this device suitable for automotive applications?

Yes, it has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1).
