SL74HC139
Dual 1-of-4 Decoder/Demultiplexer
High-Performance Silicon-Gate CMOS
The SL74HC139 is identical in pinout to the LS/ALS139. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device consists of two independent 1-of-4 decoders, each of which decodes a two-bit Address ...
