Overview
The SN74AHCU04DR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the AHCU logic series. It utilizes CMOS technology and features six independent inverting circuits within a single package. The device operates with a supply voltage range of 2 V to 5.5 V. It supports surface-mount installation in a TSSOP-14 package. The component is rated for an extended operating temperature range from -55°C to +125°C. Key electrical specifications include a propagation delay of 8 ns and output drive currents of ±8 mA.
Feature Summary
- Mil-enhanced reliability qualification for demanding environments
- Extended industrial temperature operation capability
- High-speed signal inversion performance
Applications
- Military electronic systems requiring enhanced reliability
- Automotive electronics subject to extreme thermal conditions
- Industrial control logic interfaces
Procurement Notes
Verify the specific suffix 'REP' or 'E4' against the datasheet to confirm mil-enhanced status, as standard commercial variants lack this qualification. Ensure the ordering part number matches the required temperature grade and packaging format. Confirm RoHS compliance details directly with the manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when military-grade reliability or extended temperature tolerance is required alongside high-speed CMOS logic. Compare against standard SN74AHCU04 variants if environmental stress screening is unnecessary. Verify that the TSSOP-14 footprint aligns with the PCB design constraints and that the 2V to 5.5V supply range meets system power requirements.
Part Context
This part belongs to the SN74AHCU04 family of hex inverters. The 'U' designation indicates advanced high-speed CMOS technology optimized for low power consumption and fast switching speeds. The 'REP' suffix typically denotes a specific manufacturing lot or reliability enhancement level distinct from standard commercial production runs.
Replacement Considerations
SN74AHCU04DGVR: Same logic family and function in SOIC-14 package. SN74AHCU04PWR: Commercial grade version in TSSOP-14 without mil-enhancement. SN74AHC04PW: Standard AHC series in TSSOP-14 with lower speed and no mil-enhancement.
