SEMICONDUCTOR TECHNICAL DATA
Dual 1-of-4 Decoder/
Demultiplexer
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 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 100 FETs or 25 Equivalent Gates
