MC54HC158 Datasheet (Motorola) - Quad 2-Input Data Selector/Multiplexer

MC54HC158, Quad 2-Input Data Selector/Multiplexer

INPUTS A0 *A3 (Pins 2,5,11,14) Nibble A inputs.

The data present on these pins is transferred to the outputs when the Select input is at a low level and the Output Enable input is at a low level.

The data is presented to the outputs in inverted form for the HC158.

B0 *B3 (Pins 3,6,10,

MOTOROLA 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 compatible with Standard CMOS outputs; with pullup resistors, they are compatible 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.
