SL74HCT139
Dual 1-of-4 Decoder/Demultiplexer
High-Performance Silicon-Gate CMOS
The SL74HCT139A is identical in pinout to the LS/ALS139. The SL74HCT139A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device consists of two independent 1-of-4 decoders, each of which decodes a two-bit Address to one-of-fou...
