74AHCT3G04DC,125

Overview

The Nexperia 74AHCT3G04DC,125 is a triple inverter integrated circuit manufactured using high-speed silicon-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels for compatibility with standard logic families. The device provides three independent inverters in an 8-pin VSSOP package. Key electrical characteristics include symmetrical output impedance, low power dissipation, and balanced propagation delays. It supports operation temperatures from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Triple inverter configuration with symmetrical output impedance.
• TTL input switching levels compatible with 5V logic systems.
• High noise immunity and low power dissipation.
• Robust ESD protection meeting ANSI/ESDA/JEDEC standards.

Applications

• General-purpose signal inversion in digital circuits.
• Clock signal buffering and conditioning.
• Logic level translation interfaces requiring TTL inputs.

Procurement Notes

Verify the specific suffix DC,125 corresponds to the VSSOP-8 package and tape-and-reel orientation required for your assembly line. Confirm that the AHCT series TTL input thresholds align with your system's logic voltage levels, as AHC variants differ. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number with official Nexperia documentation to confirm current production status and availability through authorized channels.

Selection Notes

Select this component when a triple inverter function is required with TTL-compatible inputs. The AHCT series is distinct from AHC due to its 4.5V minimum supply voltage and TTL input thresholds. Choose this over single inverters if space efficiency is needed. Verify that the VSSOP-8 package fits your PCB footprint constraints. Consider the ESD ratings if the application involves frequent human contact or high-static environments.

Part Context

This component belongs to the Nexperia 74AHCT3G04 family of high-speed Si-gate CMOS devices. It is part of the broader 74-series logic lineup, specifically designed for applications requiring low power consumption and high noise immunity. The device serves as a fundamental building block for digital logic designs, offering reliable performance across industrial and commercial temperature ranges.

Replacement Considerations

The 74AHCT3G04GD,125 is listed as obsolete with the 74AHCT3G04DC,125 identified as a similar available substitute. Verify pinout and package dimensions before substitution. Other triple inverters from the same family may require checking input threshold compatibility.
