SN74LVC157AQDRG4Q1

Overview

The SN74LVC157AQDRG4Q1 is an automotive-grade quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments. It operates within a supply voltage range 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 16-pin SOIC package.

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
• Mixed 3.3V/5V system environments
• Data routing and selection circuits

Procurement Notes

Verify the specific ordering suffix 'G4' indicates RoHS compliance and lead-free finish as documented in TI's packaging addendum. Confirm the SOIC (D) package type matches the design requirements. Ensure the component meets AEC-Q100 standards for automotive reliability before finalizing procurement specifications.

Selection Notes

Select this component when automotive qualification and high-speed data selection are required. The LVC logic family supports operation down to 2V, suitable for low-power applications. The 5.5V input tolerance allows direct interfacing with legacy 5V logic without additional level shifting components.

Part Context

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