74LVC2G34GV-Q100,1

Overview

The Nexperia 74LVC2G34GV-Q100,1 is a dual buffer gate in the 74LVC logic family, housed in a TSOP6 (SOT457) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Static characteristics include input leakage currents up to ±1 μA and supply current up to 4 μA. Dynamic performance specifies propagation delays ranging from 0.5 ns to 10.8 ns depending on voltage.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger inputs provide tolerance for slow rise and fall times
• Overvoltage tolerant inputs allow direct interfacing with 5 V devices

Applications

• Mixed 3.3 V and 5 V logic environments
• Automotive electronic systems
• Partial power-down applications requiring output disabling

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74 TSOP6 package configuration required for your design. Confirm that the Q100 designation aligns with automotive grade requirements. Ensure compatibility with the specified operating temperature range and voltage levels before finalizing procurement orders.

Selection Notes

Select this component when a dual non-inverting buffer with Schmitt-trigger inputs is needed for signal conditioning. The wide supply voltage range facilitates use in mixed-voltage systems. The automotive qualification makes it suitable for harsh environments where reliability under varying temperatures is critical.

Part Context

This part belongs to the 74LVC2G34-Q100 series of dual buffer gates manufactured by Nexperia. It shares functional specifications with other packages in the series, such as TSSOP6 and XSON6 variants, but differs in physical dimensions and pinout layout. The GV suffix specifically identifies the TSOP6 surface-mount package option.
