74AHCT3G04GD,125

Overview

The Nexperia 74AHCT3G04GD,125 is a triple inverter housed in an SOT765-1 (VSSOP8) package. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device provides overvoltage tolerant inputs up to 5.5 V, ensuring compatibility in mixed-voltage environments. It exhibits high noise immunity, CMOS low power dissipation, and balanced propagation delays. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Operating temperatures span from -40 °C to +125 °C.

Feature Summary

• Triple inverter configuration with TTL-compatible input levels
• Overvoltage tolerant inputs for mixed-voltage translation
• High noise immunity and symmetrical output impedance
• Robust ESD protection exceeding JEDEC Class 2 and C3 standards

Applications

• Signal inversion in digital logic circuits
• Voltage level translation between TTL and CMOS domains
• Buffering applications requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix GD corresponds to the VSSOP8 package variant when sourcing. Confirm that the application environment remains within the specified 4.5 V to 5.5 V supply voltage range to ensure proper TTL logic level operation. Ensure thermal management accounts for the maximum operating temperature of +125 °C during design integration.

Selection Notes

Select this component when TTL input thresholds are required alongside CMOS performance characteristics. The AHCT series is suitable for interfacing with legacy TTL outputs driving modern CMOS loads. The VSSOP8 package offers a compact footprint for space-constrained designs. Verify that the overvoltage tolerance meets the maximum signal amplitude present on the input lines.

Part Context

This part belongs to the Nexperia 74AHC/AHCT single-gate logic family, designed for high-speed digital applications. The AHCT variant specifically bridges the gap between Low-power Schottky TTL (LSTTL) and CMOS technologies. It shares pinout compatibility with other devices in the 74AHC3G04 series, facilitating design flexibility across different voltage domains.

Replacement Considerations

The 74AHCT3G04DC is a direct functional equivalent in the same VSSOP8 package. Other variants such as 74AHCT3G04DP (TSSOP8) or 74AHCT3G04GT (XSON8) offer identical electrical performance but require package adaptation due to differing physical footprints.
