74AHCT3G04DP,125

Overview

The Nexperia 74AHCT3G04DP,125 is a triple inverter housed in an SOT505-2 (TSSOP8) 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 symmetrical output impedance, high noise immunity, and balanced propagation delays. Latch-up performance exceeds 100 mA per JESD 78 Class II Level A. ESD protection meets ANSI/ESDA/JEDEC JS-001 class 2 for HBM and JS-002 class C3 for CDM.

Feature Summary

• Triple inverter with TTL input switching levels
• Overvoltage tolerant inputs up to 5.5 V
• Symmetrical output impedance and balanced propagation delays
• High noise immunity with CMOS low power dissipation

Applications

• Translators in mixed voltage environments
• Signal inversion in digital logic circuits
• Buffering applications requiring TTL-compatible inputs

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the AHCT variant aligns with system TTL input requirements rather than standard CMOS levels. Ensure design compliance with absolute maximum ratings to prevent damage from overvoltage or excessive current stress during operation.

Selection Notes

Select this component when TTL-level interface compatibility is required alongside high-speed inverting functionality. The AHCT series is suitable for systems operating strictly at 4.5 V to 5.5 V. Consider the TSSOP8 package for space-constrained PCB layouts requiring surface-mount assembly. Verify thermal derating requirements if operating near the upper temperature limit.

Part Context

This part belongs to the Nexperia 74AHC/AHCT family of high-speed Si-gate CMOS devices. The 74AHCT3G04 specifically denotes a triple inverter configuration with TTL-compatible inputs. It shares pinout and functional similarities with other members of the 74AHC3Gxx series but differs in input threshold characteristics to support legacy TTL interfacing.

Replacement Considerations

Direct substitutes include other 74AHCT3G04 variants from Nexperia such as the DC (VSSOP8) or GT (XSON8) packages. Cross-manufacturer equivalents must be verified for identical pin configurations, electrical characteristics, and package dimensions.
