74HC3G34DP,125

Overview

The Nexperia 74HC3G34DP,125 is a triple non-inverting buffer gate housed in an 8-lead TSSOP plastic thin shrink small outline package (SOT505-2). It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. Inputs include clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Triple non-inverting buffer configuration
• Wide supply voltage operation from 2.0 V to 6.0 V
• High noise immunity and low power consumption
• Robust ESD protection meeting JEDEC standards

Applications

• Signal buffering in mixed-voltage environments
• Line driving applications requiring high noise immunity
• General-purpose logic buffering

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status and REACH registration details prior to procurement. Ensure the component matches the required SOT505-2 package dimensions and lead specifications for the intended PCB layout.

Selection Notes

Select this component when a triple non-inverting buffer is required with a wide operating voltage range up to 6.0 V. It is suitable for designs needing high noise immunity and robust latch-up protection. Verify that the input levels align with CMOS logic requirements rather than TTL levels, which are specified for the HCT variant.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally similar to the 74HCT3G34 but utilizes CMOS input levels instead of TTL-compatible thresholds. The DP suffix indicates the TSSOP8 package variant, distinguishing it from other package options like VSSOP8.

Replacement Considerations

The 74HCT3G34DP,125 serves as a functional replacement if TTL-level inputs are acceptable. Other triple buffer gates from the same family may be considered based on package availability.
