74LS139 – Dual 1-of-4 Dcdr Demultiplexer

Black Mamba 2. So, I compared it to Demux’s Enable input. VIEWP datasheett nr 0. There is no select lines.

All operating parameters, including “Typicals” must be validated for each customer application by customer’s technical experts.

Thanks for simplifying the answer. The E enable line can be used as active low input. Before taking a look at demux, I actually took a look at mux’s datasheet, where I saw an Enable input, to enable or disable mux.

74LS Datasheet pdf – Decoder/Demultiplexer – Fairchild Semiconductor

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 74sl139 used as a data input for a 4-output demultiplexer.

If yes then how can I give it input and select lines? What, exactly, do you think the function of pins 1 and 15 are? Home Questions Tags Users Unanswered. Your explanation resolved my confusion. The device has two independent decoders, each of which accept two binary weighted inputs AAi and provide four mutually exclusive active LOW outputs O0-O3. I just better understood the concept from you than from Tom’s answer. The outputs are active low, hence the outputs that are not addressed are high. Sign up or log in Sign up using Google.
