Dual 1-of-4 Decoder/ Demultiplexer
High−Performance Silicon−Gate CMOS
MC74HC139A
The MC74HC139A is identical in pinout to the LS139. The device inputs are compatible with standard CMOS outputs; with pull−up resistors, they are compatible with LSTTL outputs.
This device consists of two independent 1−of−4 decoders, each of which decodes a two−bit Address to on...
