RoHS: Compliant
View Datasheet Manufacturer Site View Pricing & Stock

The MC74HC138A is identical in pinout to the LS138. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC138A decodes a three bit Address to one of eight active low outputs. This device features three Chip Select inputs, two active low and one active high to facilitate the demultiplexing, cascading, and chip selecting functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the other Chip Selects are held in their active states.
