The MC74HC157ADG is a 2-input quad Data Selector/Multiplexer identical in pinout to the LS157. The device inputs are compatible with standard CMOS outputs, with pull-up resistors, they are compatible with LSTTL outputs. This device routes 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in non-inverted form. A high level on the Output Enable input sets all four Y outputs to a low level.
Feature
