SN74AHC04D

Overview

The SN74AHC04D is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the AHC logic family. It contains six independent inverters housed in a 14-pin Small Outline Integrated Circuit (SOIC) package. The device operates within a supply voltage range of 2V to 5.5V and supports an extended industrial temperature range from -40°C to +125°C. Key electrical characteristics include a maximum propagation delay of 7.5ns at 5V with a 50pF load, and symmetrical output drive currents of 8mA for both high and low states.

Feature Summary

• Provides six independent single-input inverting gates within a single package
• Features CMOS technology optimized for low power consumption and high-speed operation
• Supports wide supply voltage ranges compatible with standard digital logic levels

Applications

• General-purpose signal inversion in digital circuits
• Clock signal generation and conditioning
• Data bus buffering and level shifting

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and environmental compliance. Ensure the selected variant matches the required operating temperature range and pin configuration for the target PCB layout. Cross-reference part numbers with official TI documentation to avoid confusion between similar logic families or packaging options.

Selection Notes

Select this component when six independent inverters are required in a surface-mount SOIC package. Consider the AHC series for applications demanding faster switching speeds compared to standard HC logic while maintaining low power dissipation. Verify that the 2V to 5.5V supply range aligns with the system's power rails and that the 8mA drive capability meets the load requirements.

Part Context

This component is part of the SNx4AHC04 family of hex inverters produced by Texas Instruments. It shares functional similarities with other devices in the AHC series but is distinguished by its specific SOIC-14 packaging and commercial/industrial temperature ratings. The device serves as a fundamental building block for digital logic design, offering a compact solution for signal inversion tasks.
