Dual 1-of-4 Decoder/Demultiplexer
High-Speed Silicon-Gate CMOS
KK74AC139
The KK74AC139 is identical in pinout to the LS/ALS139, HC/HCT139. The device inputs are compatible with
standard CMOS outputs; with pullup resistors, they are compatible with
LS/ALS 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.
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0 µA; 0.1 µA @ 25°C
High Noise Immunity Characteristic of CMOS Devices
ORDERING INFORMATION
Outputs Source/Sink 24 mA
