74HCT3G34GD,125

Overview

The Nexperia 74HCT3G34GD,125 is a triple buffer gate utilizing HCT logic technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-compatible input levels and includes clamp diodes on inputs for overvoltage interfacing. It is housed in an XSON8 package (SOT1096) with 8 leads.

Feature Summary

• Triple non-inverting buffer configuration
• TTL-compatible input voltage levels
• Input clamp diodes for overvoltage tolerance

Applications

• Signal buffering in digital circuits
• Line driving applications
• Interface between different logic families

Procurement Notes

Verify the specific ordering suffix GD corresponds to the XSON8 package (SOT1096). Confirm that the requested part number matches the exact manufacturer designation. Check datasheet revision history for any updates regarding marking codes or pin configurations before finalizing procurement specifications.

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS low power dissipation. Ensure the application environment stays within the specified -40 °C to +125 °C operating temperature range. Verify that the XSON8 package dimensions fit the PCB layout constraints compared to standard TSSOP alternatives.

Part Context

This component belongs to the Nexperia 74HCT3G series of single-function gates. It provides three independent buffers in a compact form factor. The HCT logic family ensures compatibility with standard TTL devices while offering improved noise immunity and lower power consumption compared to older bipolar technologies.

Replacement Considerations

The 74HC3G34GD,125 serves as a high-speed CMOS alternative with similar pinout but requires CMOS-level input voltages. The 74HCT3G34DP,125 offers identical electrical characteristics but utilizes a TSSOP8 package instead of XSON8.
