SN74AHCT04D

Overview

The SN74AHCT04D is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74AHCT00 series. It features six independent inverters designed for high-speed digital applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-compatible input levels. Key electrical parameters include a propagation delay of 6.7 ns at 5 V with a 50 pF load, an output current capability of ±8 mA, and a static power consumption of 2 µA. It functions reliably across an operating temperature range from -40 °C to +125 °C.

Feature Summary

• TTL-compatible inputs allow direct interfacing with 5V TTL logic systems without level shifting requirements.
• High-speed operation ensures low propagation delays suitable for demanding digital signal processing tasks.
• Robust electrostatic discharge protection meets JESD 22 standards for human model and charged device model testing.

Applications

• Signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Interface between 3.3V CMOS and 5V TTL logic domains

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-14 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component matches the SN74AHCT04 series specifications rather than standard HCT or AHC variants to guarantee correct voltage compatibility and performance characteristics.

Selection Notes

Select this component when TTL-level input compatibility is required alongside high-speed CMOS performance. The AHCT series bridges the gap between older TTL standards and modern CMOS technologies. Consider the SOIC-14 package constraints for PCB layout and thermal management during design integration.
