SN74AHCU04NSR

Overview

The SN74AHCU04NSR is a hex inverter manufactured by Texas Instruments, belonging to the AHCU logic series. It features six independent inverters within a single package. The device operates on a supply voltage range of 2 V to 5.5 V and supports a wide operating temperature range from -55°C to +125°C. It utilizes a 14-pin SOIC package for surface mount installation. Key electrical characteristics include a propagation delay of 8 ns, with output drive capabilities of 8 mA at low levels and -8 mA at high levels.

Feature Summary

• Mil-enhanced reliability specifications for harsh environments
• Wide industrial and extended temperature operation capability
• High-speed CMOS technology for efficient signal inversion

Applications

• Military aerospace electronic systems
• Industrial control circuitry requiring extended temperature stability
• Signal conditioning in high-reliability communication equipment

Procurement Notes

Verify the specific suffix 'REP' or equivalent military grade designation when sourcing, as standard commercial variants may lack Mil-enhanced qualification. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the exact package and temperature rating required for your design. Cross-reference with authorized distributors to validate authenticity and traceability records.

Selection Notes

Select this component when military-grade reliability is mandated alongside high-speed performance. The AHCU series offers superior speed compared to standard AHC devices while maintaining CMOS compatibility. Consider the 14-pin SOIC footprint for PCB layout constraints. Evaluate the -55°C to +125°C range against your environmental requirements to ensure adequate thermal margin for long-term operation.

Part Context

This part belongs to the SN74AHCU04 family of hex inverters. It shares functional similarities with the SN74AHCU04PWR and SN74AHCU04DGVR but differs in package type and potential qualification standards. The NSR suffix indicates an SOIC package with reel packaging. It serves as a digital logic inverter solution for applications demanding robustness beyond standard commercial grades.

Replacement Considerations

SN74AHCU04PWRG4: Commercial grade alternative in TSSOP-14 package; verify temperature range suitability. SN74AHCU04DGVR: Commercial grade alternative in SOIC-14 package; check if Mil-enhanced specs are required.
