74LVC1G34GX4Z

Overview

The Nexperia 74LVC1G34GX4Z is a single non-inverting buffer in the 74LVC logic family, housed in an X2SON4 (SOT1269-2) package with dimensions of 0.6 x 0.6 x 0.32 mm. It operates on a supply voltage range of 1.65 V to 5.5 V and supports inputs driven by 3.3 V or 5 V devices. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Static characteristics include ±32 mA output drive capability at VCC = 3.0 V. Propagation delay ranges from 1.0 ns to 11.0 ns depending on voltage and temperature.

Feature Summary

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

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Buffering data lines in low-power CMOS systems
• Partial power-down mode applications requiring backflow current prevention

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the X2SON4 form factor aligns with PCB footprint constraints. Ensure the ambient temperature rating meets operational requirements. Check RoHS compliance status against project specifications. Validate pinout compatibility with existing design layouts before finalizing procurement.

Selection Notes

Choose this component when ultra-small surface-mount packaging is critical for space-constrained designs. Select for applications requiring robust noise immunity via Schmitt triggers. Ideal for systems needing direct interface with TTL levels without additional translation components. Consider for portable electronics where low power dissipation and wide voltage operation are essential.

Part Context
