Overview
The 74LVC157APW/AUJ, produced by NXP USA Inc., is a quad 2-input multiplexer integrated circuit. This device is designed to select one of two data sources for each of its four multiplexer circuits based on the state of the select (S) and enable (E) inputs. A HIGH on the select input (S) selects data source 1, while a LOW selects data source 0. Additionally, a HIGH on the enable input (E) forces all the outputs (1Y to 4Y) to a LOW state. This multiplexer is versatile and can be used in mixed 3.3 V and 5 V applications, making it a valuable component in various electronic designs.
