MC74HC139A
Dual 1-of-4 Decoder/
Demultiplexer
High−Performance Silicon−Gate CMOS
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 one−of−four active−low outputs.
Active−low Selects are provided to facilitate the demultiplexing and
cascading functions. The demultiplexing function is accomplished by
using the Address inputs to select the desired device output, and
utilizing the Select as a data input.
