Overview
The 74LVC157APW,112 is a quad 2-input multiplexer produced by Nexperia USA Inc. This integrated circuit 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 outputs (1Y to 4Y) to LOW, providing flexible control over the output states.
