SN74HCS157DR

Overview

The SN74HCS157DR is a quadruple 2-line to 1-line multiplexer from the HCS logic series, manufactured by Texas Instruments. It features true outputs and operates within a supply voltage range of 2 V to 6 V. The device is housed in a SOIC-16 package with a maximum operating temperature of 125 °C and a minimum of -40 °C. It includes four independent multiplexing circuits, each selecting between two data inputs based on a common select line.

Feature Summary

• Provides four independent 2-to-1 data selection channels
• Operates across an extended industrial temperature range
• Compatible with standard CMOS logic levels

Applications

• Data routing in embedded systems
• Signal selection in automotive electronics
• General-purpose digital logic switching

Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-16 tape-and-reel packaging configuration. Confirm that the HCS series designation aligns with the required low-power performance specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a quad 2-to-1 multiplexer is required with wide voltage compatibility. The HCS series offers improved power consumption characteristics compared to older HC/UH variants while maintaining similar pinouts. Ensure the SOIC-16 footprint matches the PCB layout constraints.

Part Context

This part belongs to the SN74HCS157 family, which represents high-speed CMOS technology optimized for lower power dissipation. It serves as a direct functional replacement for standard SN74HC157 devices in many designs, offering enhanced electrical characteristics suitable for modern low-voltage digital applications.

Replacement Considerations

The SN74HC157DR is a compatible alternative within the same package type. Verify that the HC series voltage and speed parameters meet the specific design requirements if substituting.
