74HC3G34GD,125

Overview

The Nexperia 74HC3G34GD,125 is a triple non-inverting buffer manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2V to 6V and features push-pull outputs capable of sourcing and sinking 5.2mA. The device contains three independent logic elements, each configured as a single-bit buffer. It is housed in an SOT353 UMT5 package, which measures 1.4mm x 0.8mm x 0.45mm. The component supports surface mount installation and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Triple non-inverting buffer configuration providing signal buffering for three independent channels
• Push-pull output stage design ensuring robust drive capability with defined high and low states
• Wide operating voltage compatibility supporting both 2V and 6V logic systems
• Compact UMT5 package footprint optimized for space-constrained printed circuit board layouts

Applications

• General-purpose signal buffering in consumer electronics
• Level shifting between different voltage domains in mixed-signal circuits
• I/O expansion on microcontroller boards requiring additional drive strength
• Signal routing in portable devices with limited board real estate

Procurement Notes

Verify the specific suffix GD against official Nexperia documentation to confirm the UMT5 package type and tape-and-reel specifications. Ensure that the intended application voltage remains within the 2V to 6V operational limits. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the manufacturing process.

Selection Notes

Select this component when a compact triple buffer is required for non-inverting signal paths. The UMT5 package offers a smaller footprint compared to standard TSSOP or QFN options. Verify that the 5.2mA output current meets the load requirements of the destination circuitry. Consider the wide temperature range if the environment exceeds standard commercial limits.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices from Nexperia. The HC series is designed to be pin-compatible with Low-power Schottky TTL (LSTTL) standards while offering higher speed and lower power consumption. The 3G34 designation specifically indicates a triple buffer function within this family.

Replacement Considerations

The 74HC3G34DP,125 serves as a functional substitute but utilizes an 8-TSSOP package rather than the UMT5 form factor. Designers must evaluate the mechanical size difference and verify pin-to-pin compatibility before swapping components.
