Overview
The SN74HC157PWRG4, produced by Texas Instruments, is a quadruple 2-to-1 multiplexer/data selector integrated circuit. This component is part of the 74HC series and is designed to select one of two data sources for each of its four channels. The device is controlled by the same address select (A/B) input and strobe (G) input for all channels. A high level at the strobe terminal forces all outputs low, providing a simple and efficient way to manage data selection in various digital systems.
