SN74AHCT04N

Overview

The SN74AHCT04N is a hex inverter integrated circuit manufactured by Texas Instruments. It belongs to the 74AHCT logic family, providing six independent inverters that perform the Boolean function Y = NOT A. The device operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels, allowing direct interfacing with 5-V CMOS and TTL devices. It utilizes advanced CMOS technology to achieve high-speed operation while maintaining low power consumption. The component is designed for surface-mount or through-hole applications depending on the specific package variant, ensuring reliable signal inversion in digital logic circuits.

Feature Summary

• TTL-compatible input levels enable direct connection to 5-V TTL logic systems without additional level shifting.

Applications

• Signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Data line buffering and inversion

Procurement Notes

Verify the exact package type (e.g., DIP-14) against the datasheet before procurement, as the 'N' suffix typically denotes a specific leaded package variant which may differ from tape-and-reel options. Confirm RoHS compliance status and operating temperature range requirements match the target application environment. Ensure the supplier provides official documentation to validate the part number authenticity and revision history.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output drive capabilities. It is suitable for designs needing high noise immunity and low static power dissipation. Consider the physical package constraints and pinout compatibility with existing PCB footprints. Verify that the 4.5 V to 5.5 V supply voltage range aligns with the system power rails.

Part Context

This part is a member of the Texas Instruments 74AHCT series, which bridges the performance gap between standard 74HC and 74HCT families. The AHCT series offers faster switching speeds than HCT while maintaining TTL input thresholds. This specific model provides six inverters in a single package, making it efficient for space-constrained digital designs requiring multiple logic inversions.

Replacement Considerations

SN74AHCT04DR: Same logical function but in SOIC-14 package. SN74AHCT04PWR: Same logical function but in TSSOP-14 package. SN74AHCT04NSR: Same logical function but in SOIC-14 package with reel packaging. Verify package dimensions and pin compatibility before substitution.
