74LVC1G34GZYL

Overview

The Nexperia 74LVC1G34GZYL is a single non-inverting buffer within the LVC logic family, designed for surface-mount applications in XSON-5 packages. It operates across a wide supply voltage range of 1.1 V to 3.6 V, supporting mixed-voltage environments. The device features Schmitt-trigger inputs for noise immunity and includes I_OFF circuitry to prevent backflow current during partial power-down states. It complies with JEDEC standards for low-voltage operation and offers robust ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Provides level translation between different voltage domains via overvoltage tolerant inputs.
• Incorporates Schmitt-trigger action to ensure signal integrity with slow input transitions.
• Enables safe partial power-down operation through integrated I_OFF output disabling.

Applications

• Translating signals between 3.3 V and 5 V digital systems.
• Buffering data lines in mixed-voltage embedded controllers.
• Interface circuits requiring protection against backflow current during power cycles.

Procurement Notes

Verify the specific suffix 'YL' against official Nexperia documentation to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with design tools by sourcing the correct ECAD model. Confirm RoHS compliance status directly from the manufacturer's latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a single-channel buffer is required for low-voltage logic families operating up to 3.6 V. The XSON-5 package suits space-constrained designs. Verify that the 1.1 V minimum supply meets system requirements, as standard LVC variants often start at 1.65 V. Check thermal resistance values if high ambient temperatures are expected.

Part Context

This part belongs to the Nexperia 74LVC series, which provides low-voltage CMOS performance. The '1G' designation indicates a single gate configuration, while '34' identifies it as a non-inverting buffer. The 'GZYL' suffix specifies the XSON-5 package variant and reel packaging type, distinguishing it from other physical form factors like TSSOP or XSON-6.

Replacement Considerations

The 74LVC1G34GV,125 serves as a functional substitute in TSOP-5 packaging. The 74LVC1G34GM,115 offers an alternative in XSON-6 format. Verify pinout compatibility and package footprint differences before swapping these parts in existing hardware designs.
