CD74AC157M96

Signal Switches, Multiplexers, Decoders Overview

The CD74AC157M96 is a high-speed CMOS quadruple 2-line to 1-line multiplexer designed for general-purpose data selection in logic systems. It operates within a supply voltage range of 1.5 V to 5.5 V, providing balanced noise immunity at 30% of the supply voltage. The device features four independent multiplexing circuits, each selecting one of two data inputs based on a common select line and an enable input. Packaged in a 16-SOIC (Narrow) surface-mount case, it offers propagation delays typical of AC speed performance while maintaining low power consumption characteristics inherent to CMOS technology.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix M96 indicates the tape-and-reel packaging format when ordering. Confirm that the 1.5 V minimum operating voltage requirement aligns with your system's power rails, as this differs from standard 5 V-only logic families. Ensure ESD precautions are observed during handling due to the CMOS input structure. Cross-reference the datasheet for exact pinout compatibility if replacing legacy components.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple independent 2-to-1 signal paths are required within a single package. It is suitable for applications demanding operation below 5 V where standard HC or HCT families may not suffice. Consider the SOIC-16 footprint constraints and thermal dissipation requirements for your PCB layout. Verify that the input voltage levels match your source logic outputs across the entire operating temperature range.
