74HC157D

Signal Switches, Multiplexers, Decoders Overview

The Toshiba Semiconductor and Storage 74HC157D is a high-speed CMOS quad 2-input multiplexer housed in a 16-pin SOIC package. It operates within a supply voltage range of 2V to 6V, with a typical propagation delay of 10ns at 5V. The device features four independent circuits, each selecting one of two data inputs based on a common select line, providing true outputs. It supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.
