High–Performance Silicon–Gate CMOS
The MC54/74HC139A is identical in pinout to the LS139. The device
inputs are compatible with standard CMOS outputs; with pullup 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.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0
