74LVC3G34GD/S470,1

Overview

The Nexperia 74LVC3G34GD/S470,1 is a triple buffer featuring Schmitt-trigger inputs and IOFF circuitry for partial power-down protection. It operates within a supply voltage range of 1.65 V to 5.5 V and supports overvoltage tolerant inputs up to 5.5 V. The device provides an output drive capability of ±24 mA at VCC = 3.0 V and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36. It is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Triple buffer configuration with Schmitt-trigger action on all inputs for tolerance of slow signal transitions.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents.
• Overvoltage tolerant inputs allow direct interfacing between mixed 3.3 V and 5 V logic environments.

Applications

• Signal buffering in mixed-voltage digital systems
• Line driving applications requiring noise immunity
• Partial power-down mode circuit protection

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and marking code. Confirm availability status as product lines may undergo discontinuation or revision updates. Ensure design compliance with the latest data sheet specifications before finalizing procurement orders.

Selection Notes

Select this component when a triple non-inverting buffer with Schmitt-trigger inputs is required. It is suitable for designs needing robust noise immunity and compatibility across 1.65 V to 5.5 V supply rails. Verify that the SOT996-2 package variant matches the target PCB footprint requirements.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices manufactured by Nexperia. The 74LVC3G34 series specifically denotes a triple buffer. The GD suffix indicates a specific package variant, historically associated with the XSON8U form factor, though recent datasheet revisions note changes to available package types within the series.

Replacement Considerations

Public confirmed substitute: 74LVC3G34DC-Q100H (Nexperia). This alternative offers automotive qualification via AEC-Q100 certification while maintaining functional equivalence as a triple buffer.
