74HC3G34DC,125

Overview

The Nexperia 74HC3G34DC,125 is a triple buffer gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and features CMOS low power dissipation with high noise immunity. The device includes input clamp diodes for interfacing with voltages exceeding VCC. It provides latch-up performance exceeding 100 mA per JESD 78 Class II Level B and complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V). ESD protection exceeds 2000 V HBM and 1000 V CDM. The component is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Triple non-inverting buffer configuration
• Wide supply voltage compatibility from 2.0 V to 6.0 V
• Input clamp diodes enable direct interface to voltages above VCC

Applications

• Signal buffering in digital logic circuits
• Voltage level translation between CMOS components
• Interface isolation for inputs exceeding supply voltage

Procurement Notes

Verify the specific ordering suffix DC corresponds to the VSSOP-8 package (SOT765-1) as defined in the official Nexperia datasheet. Confirm that the 125 suffix indicates the standard tape and reel packaging format. Ensure compliance with RoHS directives and REACH regulations before finalizing procurement specifications.

Selection Notes

Select this component when a triple buffer is required for signals operating between 2.0 V and 6.0 V. It is suitable for applications needing high noise immunity and robust latch-up protection. Verify that the VSSOP-8 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It serves as a fundamental building block for signal conditioning and routing in complex digital systems. The DC variant specifically denotes the very thin shrink small outline package, distinguishing it from other physical form factors within the same logical family.

Replacement Considerations

Direct pin-compatible replacements include the 74HCT3G34DC,125 for TTL-level input requirements. Other generic triple buffers may require verification of voltage ranges and output drive capabilities.
