74ACT139 Datasheet PDF

Data sheet acquired from Harris Semiconductor SCHS235 CD74AC139, CD74ACT139 Dual 2-to-4-Line Decoder, Demultiplexer Description The CD74AC139 and CD74ACT139 are dual 2-to-4-line decoders, demultiplexers that utilize the Harris Advanced CMOS Logic technology. These devices contain two independent binary to one-of-four decoders, each with a single active LOW enable input (1E or 2E). Data on the sel

MC74AC139 MC74ACT139 Dual 1 of 4 Decoder, Demultiplexer The MC74AC139, 74ACT139 is a high-speed, dual 1-of-4 decoder, demultiplexer. The device has two independent decoders, each accepting two inputs and providing four mutually-exclusive active-LOW outputs. Each decoder has an active-LOW Enable input which can be used as a data input for a 4-output demultiplexer. Each half of the MC74AC139, 74ACT
