The MC74AC157/74ACT157 is a high-speed quad 2-input multiplexer. Four bits of data from two sources can be selected using the common Select and Enable inputs. The four outputs present the selected data in the true (noninverted) form. The MC74AC157/74ACT157 can also be used as a function generator.
This document provides technical specifications for the Motorola MC74AC157 and MC74ACT157, which are high-speed quad 2-input multiplexers. The device allows four bits of data from two sources to be selected using common Select and Enable inputs, presenting the selected data in a true (noninverted) form.
