Overview
The 74LVC157APW-Q100J, produced by Nexperia USA Inc., is a quad 2-input multiplexer integrated circuit. This device is part of the 74LVC family, known for its low-voltage CMOS logic and compatibility with both 3.3 V and 5 V logic levels. The 74LVC157A features select (S) and enable (E) inputs, allowing for the selection of data sources and control over the output states. A HIGH on the select input (S) selects data source 1, while a LOW selects data source 0. A HIGH on the enable input (E) forces all outputs to LOW, providing additional control over the multiplexing operation.
