CD74ACT257M TI Multiplexer | 16-SOIC | 4.5V-5.5V, 4-Channel 2:1

Product Overview

The CD74ACT257M from Texas Instruments is a high-speed CMOS quad 2-input multiplexer with 3-state outputs. It operates from a single 4.5V to 5.5V supply and is designed for digital data selection and bus-oriented applications. The device features four multiplexers, each with two data inputs (A and B) and a common select input (S). The outputs are enabled by an active-low output enable (OE) input. When OE is high, all outputs are in the high-impedance state. The CD74ACT257M is offered in a 16-pin SOIC package, making it suitable for space-constrained designs.
