74LVC3G34GD,125

Overview

The Nexperia 74LVC3G34GD,125 is a triple buffer from the LVC logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device includes Schmitt-trigger action for noise immunity and IOFF circuitry for partial power-down applications. It supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Triple non-inverting buffer with Schmitt-trigger inputs
• IOFF circuitry prevents backflow current during power-down
• Overvoltage tolerant inputs compatible with mixed voltage environments

Applications

• Translators in mixed 3.3 V and 5 V environments
• Partial power-down applications requiring output disabling
• Signal buffering with high noise immunity requirements

Procurement Notes

Verify the specific package type against the ordering information table. The datasheet lists packages such as TSSOP8 (SOT505-2), VSSOP8, and XSON8 variants. Ensure the suffix matches the required physical footprint and lead configuration for the target PCB design.

Selection Notes

Select this component when a triple buffer with Schmitt-trigger inputs is required. It is suitable for applications needing direct interface with TTL levels or operation across a wide voltage range. Verify that the thermal dissipation limits align with the ambient temperature conditions of the final assembly.

Part Context

This part belongs to the 74LVC3G34 series of triple buffers manufactured by Nexperia. The series provides multiple package options including TSSOP, VSSOP, and various XSON formats. All variants share identical electrical characteristics and functionality despite physical differences.

Replacement Considerations

Other packages within the same logical family, such as 74LVC3G34DP or 74LVC3G34GS, offer equivalent electrical performance. Substitution requires verifying pin compatibility and physical dimensions.
