SN74LVC157ADE4

Overview

The SN74LVC157ADE4 is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments SN74LVC157A series. It integrates 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, ensuring compatibility with low-voltage digital systems. Key electrical specifications include a maximum propagation delay of 7 ns and an operating temperature range from -40°C to +125°C. It features CMOS technology for efficient power consumption and supports surface-mount installation.

Feature Summary

• Integrates four independent 2-to-1 multiplexers for compact data routing
• Operates across a wide supply voltage range from 1.65 V to 3.6 V
• Supports high-speed signal switching with low propagation delay
• Designed for robust performance in extended industrial temperature ranges

Applications

• Data routing in embedded control systems
• Signal selection in communication interfaces

Procurement Notes

Verify the specific suffix 'E4' indicates environmental compliance or lead-free status as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the order quantity aligns with manufacturing needs without relying on distributor stock estimates. Cross-reference the datasheet revision date to ensure current electrical characteristics are applied.

Selection Notes

Select this component when multiple independent 2-to-1 signal paths are required in a space-constrained design. The LVC logic family offers lower power consumption compared to older standards while maintaining compatible pinouts. Consider the 7 ns delay for timing-critical applications within the specified voltage and temperature limits.

Part Context

This part belongs to the SN74LVC157A family of quadruple multiplexers. It shares functional similarities with other 74-series logic devices but utilizes advanced CMOS technology for improved efficiency. The DE4 suffix typically denotes specific manufacturing or compliance attributes defined by Texas Instruments for this specific variant.

Replacement Considerations

Compatible substitutes include SN74LVC157APWR and SN74LVC157ANSR. Verify package compatibility (TSSOP vs. SOIC) and electrical parameter equivalence before substitution.
