概要
説明
The 74FCT157T is a high-speed quad 2-input multiplexer. Common applications of the 74FCT157T are to move data from two different groups of registers to a common bus to use as a function generator. The 74FCT157T can generate any four of the 16 different functions of two variables with one variable common. The 74FCT157T operates at -40C to +85C
