SN74LVC157AWBQBRQ1

Overview

The SN74LVC157AWBQBRQ1 is an automotive-grade quadruple 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates from a supply voltage of 2V to 3.6V and features inputs that accept voltages up to 5.5V, enabling translation in mixed-voltage systems. The device provides a maximum propagation delay of 5.4ns at 3.3V and includes ESD protection exceeding 2000V per MIL-STD-883. It is housed in a WQFN-16 package with dimensions of 3.5mm x 2.5mm.

Feature Summary

• Qualified for automotive applications
• ESD protection exceeds 2000V per MIL-STD-883, method 3015
• Inputs accept voltages to 5.5V

Applications

• Automotive electronic systems requiring data selection
• Mixed 3.3V/5V system environments as a translator
• Digital logic circuits utilizing quadruple multiplexing

Procurement Notes

Verify the specific ordering suffix matches the required package type and reel quantity. Confirm RoHS compliance and lead finish details against the latest Package Option Addendum. Ensure the component status is listed as Active Production before finalizing procurement plans.

Selection Notes

Select this component when automotive qualification and high-speed data routing are required. The wide input voltage tolerance allows compatibility with 5V logic sources while operating on lower supply rails. Verify thermal requirements align with the junction-to-ambient resistance specifications for the WQFN package.

Part Context

This part belongs to the SN74LVC157A-Q1 series, designed specifically for automotive use. It functions as a quad multiplexer, selecting between two data inputs for four independent outputs based on a common address select line and an active-low output strobe.

Replacement Considerations

Catalog versions such as SN74LVC157A exist but lack automotive qualification. Other variants like SN74LVC157ADRQ1 or SN74LVC157AQPWRQ1 offer different packages (SOIC, TSSOP) within the same family.
