SN74AHCT04NSR

Overview

The SN74AHCT04NSR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74AHCT04 series. It utilizes advanced CMOS technology and features TTL-compatible inputs, allowing direct interfacing with 5V TTL logic levels. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a typical propagation delay of 6.7 ns at 5 V with a 50 pF load, a static current of 2 µA, and an output drive capability of ±8 mA. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• TTL-compatible input levels for seamless integration with 5V logic systems
• Advanced CMOS construction ensuring low power consumption and high noise immunity
• Robust electrostatic discharge protection exceeding standard requirements

Applications

• General-purpose digital signal inversion in computing equipment
• Clock signal generation and conditioning circuits
• Memory interface buffering and level translation

Procurement Notes

Verify the specific suffix 'NSR' against the manufacturer's official documentation to confirm package type, tape-and-reel specifications, and RoHS compliance status. Ensure the ordering part number matches the exact functional variant required for your design, as suffixes may indicate differences in packaging or environmental certifications rather than electrical performance.

Selection Notes

Select this component when a hex inverter with TTL-compatible inputs is required for 5V logic applications. The AHCT series offers a balance of speed and power efficiency suitable for general digital logic. Consider the NSR suffix for surface-mount assembly needs and verify that the 4.5V to 5.5V supply range aligns with your system's power rails.

Part Context

This component is part of the SN74AHCTxx family, which bridges the gap between older TTL logic standards and modern CMOS technologies. The SN74AHCT04 specifically provides six independent inverters, making it a fundamental building block for digital logic designs requiring signal inversion or wave shaping within standard 5V logic environments.

Replacement Considerations

Publicly confirmed substitute part numbers include SN74AHCT04DR and SN74AHCT04DWR from Texas Instruments. These alternatives share the same logical function and electrical characteristics but may differ in package style or reel quantity.
