74LVC3G34DC,125

Overview

The Nexperia 74LVC3G34DC,125 is a triple buffer featuring Schmitt-trigger inputs and overvoltage tolerance up to 5.5 V. 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 utilizes a VSSOP8 (SOT765-1) package with an 8-lead configuration. It includes IOFF circuitry for partial power-down applications, preventing backflow current when powered down.

Feature Summary

• Triple non-inverting buffer with Schmitt trigger inputs for noise immunity
• Overvoltage tolerant inputs allowing direct interfacing with 5 V logic
• IOFF circuitry prevents damaging backflow current during partial power-down

Applications

• Translators in mixed 3.3 V and 5 V environments
• Wave and pulse shaping for noisy environments
• Buffering signals between different voltage domains

Procurement Notes

Verify the specific ordering suffix ',125' corresponds to the VSSOP8 package variant SOT765-1. Confirm that the required operating temperature range extends to +125 °C, as specified in the product data sheet revision 16. Ensure design compatibility with the 5.5 V input tolerance and check static characteristics against system leakage requirements.

Selection Notes

Select this component when a triple buffer with Schmitt trigger action is required for signal conditioning. The VSSOP8 package offers a compact footprint suitable for space-constrained designs. Verify that the application benefits from the high noise immunity provided by the Schmitt triggers and requires protection against backflow currents via the integrated IOFF functionality.

Part Context

This part belongs to the 74LVC family of CMOS logic devices, designed for low-voltage operation. The '3G' designation indicates three independent gates within a single package. The 'DC' suffix specifically identifies the VSSOP8 plastic very thin shrink small outline package, distinguishing it from TSSOP or XSON variants within the same logical function family.

Replacement Considerations

Check for other 74LVC3G34 variants such as 74LVC3G34DP (TSSOP8) if package changes are acceptable. Verify functional equivalence for any cross-manufacturer replacements to ensure matching pinouts and electrical specifications.
