Overview
The SN74LVC157AQDREP is a Mil Enhanced Quad 2-to-1-Line Multiplexer from the SN74LVC157A series, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 3.6 V and features a propagation delay of 7 ns. The device contains four independent circuits and is housed in an SOIC-Narrow-16 package. It supports surface mount installation and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Mil Enhanced reliability for demanding environments
- Quad configuration with four independent 2-to-1-line selectors
- Wide operating voltage range supporting low-power applications
Applications
- Military-grade data routing systems
- High-reliability signal selection circuits
- Industrial control logic interfaces
Procurement Notes
Verify the specific suffix 'REP' indicates Mil Enhanced status as per official documentation. Confirm RoHS compliance details directly from the manufacturer's datasheet. Ensure the SOIC-Narrow-16 package dimensions match your PCB footprint requirements. Check for any specific handling instructions related to the enhanced qualification level.
Selection Notes
Select this component when military-grade reliability is required alongside LVC logic performance. Compare against standard SN74LVC157 variants if environmental hardening is not necessary. Verify that the 7 ns propagation delay meets system timing constraints. Ensure the 2 V to 3.6 V supply range aligns with the target power architecture.
Part Context
This part belongs to the SN74LVC157A family of multiplexers. The 'A' variant typically denotes improved specifications over earlier versions. The 'Q1' or similar suffixes often indicate automotive or qualified versions, while 'REP' specifies the Mil Enhanced tier. This distinguishes it from standard commercial grade logic ICs.
Replacement Considerations
SN74LVC157AQDRG4Q1 is listed as a related variant. Verify pinout compatibility and electrical parameter equivalence before substitution. Standard SN74LVC157 parts lack the Mil Enhanced qualification and may not be suitable replacements.
