Overview
The 74HC157PW-Q100,118 is a quad 2-input multiplexer produced by Nexperia USA Inc. This device is part of the 74HC series and is designed to select one of two data sources based on the state of the select (S) input. A HIGH on the S input selects data source 1, while a LOW selects data source 0. Additionally, a HIGH on the enable (E) input forces all the outputs (1Y to 4Y) to LOW, allowing for flexible control over the data path.
The device is available in a TSSOP16 package and is specified to operate over a wide temperature range from -40 °C to +125 °C, making it suitable for various industrial and automotive applications.
