SN74LVC157AQDRQ1

Overview

The SN74LVC157AQDRQ1 is an automotive-grade quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments. It belongs to the LVC logic series and features four independent multiplexing circuits. The device operates within a supply voltage range of 2 V to 3.6 V. It exhibits a propagation delay of 7 ns. The component supports surface-mount installation in a TSSOP-16 package. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for enhanced reliability
• Quad configuration providing four independent 2-to-1 data selection channels
• Low-voltage operation capability supporting systems powered between 2 V and 3.6 V

Applications

• Automotive infotainment system data routing
• In-vehicle network signal switching
• Dashboard control unit input selection

Procurement Notes

Verify the specific suffix 'QDRQ1' matches the required TSSOP-16 package and automotive grade designation. Confirm that the AEC-Q100 qualification status aligns with your vehicle's reliability requirements. Ensure the 2 V to 3.6 V operating voltage range is compatible with your target power supply rails before finalizing procurement.

Selection Notes

Select this component when automotive certification is mandatory for data multiplexing applications. It is suitable for designs requiring low voltage operation below 5 V. Consider the 7 ns propagation delay for timing-critical automotive bus interfaces. Verify that the TSSOP-16 footprint fits the available PCB space constraints.

Part Context

This part is a member of the SN74LVC157A family, which includes standard industrial variants. The 'Q1' suffix denotes automotive qualification, distinguishing it from non-automotive versions like the SN74LVC157ADRG4. It serves as a specialized version designed for harsh automotive environments while maintaining functional compatibility with the broader LVC logic family.
