SEMICONDUCTOR TECHNICAL DATA
Quad 2-Input Data Selector/Multiplexer High- Performance Silicon- Gate CMOS
The MC54/74HC158 is identical in pinout to the LS158. The device inputs are patible with Standard CMOS outputs; with pullup resistors, they are patible with LSTTL outputs. These devices route 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in inverted form for the HC158. A high level on the Output Enable input sets all four Y outputs to a high level for the HC158. w
