SN74LS157NS TI Quad 2-Input Multiplexer | 16-SO | 4.75V-5.25V, 8mA Output

Product Overview

The SN74LS157NS is a high-speed quad 2-input multiplexer from Texas Instruments, designed to select one of two 4-bit data sources under control of a common Select input. It features a strobe (enable) input that forces all outputs low when high. The device is fabricated using advanced Schottky barrier diode technology for enhanced speed and power efficiency. Housed in a 16-pin SOIC package, it is ideal for space-constrained applications requiring reliable data routing.
