CD74ACT253E TI Multiplexer | 16-PDIP | Dual 4:1, 4.5V-5.5V

Product Overview

The CD74ACT253E from Texas Instruments is a high-speed dual 4-input multiplexer with 3-state outputs, designed for digital data selection and routing. Fabricated with advanced CMOS technology, it operates from a 4.5V to 5.5V supply, offering low power consumption and high noise immunity. The device features two independent 4-line to 1-line multiplexers with common select inputs (S0, S1) and individual output enable controls (1OE, 2OE). When an output enable is high, the corresponding output is in a high-impedance state, allowing bus-oriented applications. The CD74ACT253E is available in a 16-pin PDIP package, suitable for through-hole mounting in industrial and consumer electronics.
