MC54HC251 - 8-Input Data Selector/Multiplexer
MOTOROLA SEMICONDUCTOR TECHNICAL DATA 8-Input Data Selector/ Multiplexer with 3-State Outputs High Performance Silicon Gate CMOS The MC54/74HC251 is identical in pinout to the LS251.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This device selects one of the eight binary Data Inputs, as determined by the Address Inputs.
The Output Enable pin must be a low level for the selected data to appear at the o
