74LVC1G34GW-Q100H

Overview

The Nexperia 74LVC1G34GW-Q100H is a single non-inverting buffer in a TSSOP5 (SOT353-1) package. It operates on a supply voltage range of 1.65 V to 5.5 V with an input voltage tolerance up to 5.5 V. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. It supports output drive currents of ±24 mA at 3.0 V and ±32 mA at higher voltages, with propagation delays ranging from 1.0 ns to 11.0 ns depending on the supply voltage.

Feature Summary

• Schmitt-trigger action provides tolerance for slow input rise and fall times
• IOFF circuitry prevents damaging backflow current during partial power-down
• Overvoltage tolerant inputs allow direct interfacing with 3.3 V or 5 V devices
• Qualified to AEC-Q100 Grade 1 standards for automotive applications

Applications

• Mixed 3.3 V and 5 V logic environments
• Automotive electronic systems
• Partial power-down mode operation

Procurement Notes

Verify the specific suffix 'GW' corresponds to the TSSOP5 plastic thin shrink small outline package (SOT353-1). Confirm the temperature range requirement matches the -40 °C to +125 °C specification listed for this package type. Ensure the application design accounts for the specified total power dissipation derating characteristics above 74 °C.

Selection Notes

Select this component when a single-channel non-inverting buffer with high noise immunity is required. The integrated Schmitt trigger makes it suitable for signals with slow transitions. The wide supply voltage range allows flexibility in low-power designs down to 1.65 V while maintaining compatibility with standard 5 V logic levels through overvoltage tolerant inputs.

Part Context

This part belongs to the 74LVC1G34-Q100 family of single buffers. Other package options within this family include the SC-74A (GV) and XSON5 (GZ) variants, all sharing identical electrical specifications and operating temperatures. The GW variant specifically utilizes the SOT353-1 footprint.

Replacement Considerations

Direct pin-compatible substitutes within the same family include 74LVC1G34GV-Q100 and 74LVC1G34GZ-Q100.
