SN74LVC157ANS

Overview

The SN74LVC157ANS is a quad 2-input to 1-output data selector/multiplexer from Texas Instruments, belonging to the LVC logic family. It features four independent multiplexers in a single SOIC-16 package. The device operates within a supply voltage range of 1.65 V to 3.6 V and supports propagation delays as low as 7 ns. It is designed for surface-mount installation with an operating temperature range spanning from -40°C to +125°C.

Feature Summary

• Integrates four independent 2-to-1 multiplexers into a single integrated circuit
• Operates across a wide supply voltage range supporting low-voltage digital systems
• Provides high-speed signal selection with low propagation delay characteristics
• Compatible with both CMOS and TTL input logic levels

Applications

• Data routing in embedded control systems
• Signal selection interfaces for microcontrollers
• Address decoding circuits
• Digital logic level translation stages

Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the ordering part number matches the required industrial temperature grade and RoHS compliance status before procurement.

Selection Notes

Select this component when a compact solution for multiple 2-to-1 signal paths is required within low-voltage designs. Consider the SOIC-16 footprint constraints and verify that the 3.6 V maximum supply voltage aligns with the target system power rails.

Part Context

This part belongs to the SN74LVC157A series of multiplexers. It serves as a standard logic interface component for managing multiple data inputs. The LVC family offers improved performance over older logic families while maintaining compatibility with existing digital design architectures.

Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74LVC157APWR or SN74LVC157AQPWREP if different packaging or automotive qualification is needed.
