74ACT157MTCX

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74ACT157MTCX is a quad 2-input multiplexer housed in a 16-lead Thin Shrink Small Outline Package (TSSOP). It operates within a voltage range of 2.7V to 3.6V and supports output drive currents of 24mA high and 24mA low. The device functions as a single-pole quadruple data selector, providing four independent 2-to-1 multiplexing paths with active-low enable functionality.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure component authenticity. Confirm that the TSSOP package dimensions match your PCB footprint requirements. Check for any RoHS compliance markings if environmental regulations apply to your assembly process. Ensure storage conditions adhere to moisture sensitivity level guidelines before reflow soldering.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a compact solution for multiple signal paths is required. The ACT series offers faster switching speeds compared to standard HC logic families. The TSSOP package provides a space-efficient alternative to larger DIP or SOIC packages for dense board layouts. Ensure supply voltage remains within the specified 2.7V to 3.6V range for optimal performance.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices. It serves as a functional equivalent to other quad multiplexers in the industry but is distinguished by its specific pinout and package configuration. The MTCX suffix indicates the TSSOP package type and tape-and-reel packaging format for automated assembly.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference documents indicate CD74ACT157PWR from Texas Instruments as a compatible alternative. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement device meets the same voltage and current drive requirements.
