SN74AS157N TI Multiplexer | 16-PDIP | 4-Ch 2-Input, 4.5V-5.5V

Product Overview

The SN74AS157N is a high-speed quad 2-input multiplexer from Texas Instruments, designed for data selection and routing in digital systems. It features four independent multiplexer channels, each with two data inputs (A and B) and a common select input (S). The device operates from a 4.5V to 5.5V supply and is housed in a 16-pin PDIP package, making it suitable for through-hole PCB assembly. With typical propagation delays of 6ns and low power consumption, it is ideal for high-performance computing and communication applications.
