SN74ALS157AN TI Logic Gates | 16-PDIP | Quad 2-to-1 Data Selector/Multiplexer

Product Overview

The SN74ALS157AN is a high-performance quad 2-to-1 data selector/multiplexer from Texas Instruments, designed for digital logic applications requiring fast and reliable data routing. It features four independent multiplexers, each with two data inputs (A and B) and a common select input (S). The outputs (Y) follow the selected input based on the logic level of S. This device is fabricated using advanced low-power Schottky technology, providing a balance of speed and power consumption. It operates over a wide supply voltage range of 4.5V to 5.5V and is offered in a 16-pin plastic DIP package (16-PDIP), making it suitable for through-hole PCB assembly.
