MC74HC139A
Dual 1of4 Decoder/
Demultiplexer
HighPerformance SiliconGate CMOS
The MC74HC139A 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 1of4 decoders, each of
which decodes a twobit Address to oneoffour activelow outputs.
Activelow 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 A
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
