SN74AHCT04DR

Overview

The SN74AHCT04DR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74AHCT04 logic series. It features six independent inverters that perform the Boolean function Y = A. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes CMOS technology with TTL-compatible input levels. It is housed in a SOIC-14 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Contains six independent inverter circuits for signal inversion
• TTL-compatible inputs allow direct interfacing with 5V TTL logic systems
• CMOS output structure provides push-pull drive capability

Applications

• Signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Level shifting between 3.3V and 5V logic domains

Procurement Notes

Verify the specific suffix DR indicates the SOIC-14 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or certified distributor channels. Ensure the component matches the SN74AHCT04 series specifications regarding voltage and speed before integration into designs requiring strict timing constraints.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance characteristics. It serves as a suitable replacement for legacy 74HCT04 devices where higher speed or improved noise immunity is needed. Consider the SOIC-14 package dimensions for PCB layout compatibility and verify thermal requirements for the intended operating environment.

Part Context

This part belongs to the Texas Instruments SN74AHCT04 family of hex inverters. The AHCT series combines the high-speed performance of Advanced High-Speed CMOS (AHC) technology with TTL-compatible input thresholds. This hybrid approach facilitates easy migration from older 74HCT designs while offering improved electrical characteristics and lower power consumption compared to standard HC series alternatives.
