SN74LVC157DR

Overview

The SN74LVC157DR is a quad 2-input to 1-line data selector manufactured by Texas Instruments. It belongs to the LVC logic family and operates within a supply voltage range of 2 V to 3.6 V. The device features four independent multiplexers in a single package, providing efficient signal routing capabilities. It utilizes a 16-pin SOIC-Narrow surface-mount package suitable for automated assembly. The component supports a maximum propagation delay of 7 ns and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates four independent 2-to-1 multiplexers for compact signal selection
• Operates with low-voltage power supplies ranging from 2 V to 3.6 V
• Ensures high-speed data switching with a propagation delay of 7 ns
• Supports robust operation across extended industrial temperature environments

Applications

• Data routing in embedded control systems
• Signal selection in digital communication interfaces
• Address/data bus multiplexing in microcontroller circuits

Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-16 package and standard commercial grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the exact functional requirements and pinout configuration defined in the SN74LVC157A datasheet to prevent integration errors.

Selection Notes

Select this component when designing circuits requiring multiple independent 2-to-1 signal paths within a limited footprint. The LVC series offers compatibility with modern low-voltage logic families while maintaining sufficient drive capability. Consider the 16-pin narrow SOIC package constraints regarding PCB real estate and thermal dissipation requirements during layout planning.

Part Context

This part is a member of the SN74LVC157A series, which includes variants with different packaging options such as TSSOP and PWREP. The 'DR' designation specifically identifies the SOIC-Narrow-16 surface-mount package variant. All members share identical logical functionality but differ in physical dimensions and mounting characteristics.

Replacement Considerations

SN74LVC157AQDREP: Automotive-grade version with enhanced reliability specifications. SN74LVC157APWR: Alternative TSSOP-16 package variant with similar electrical performance.
