So, I was confused.

So, I compared it to Demux’s Enable input. Sign datasheeet using Facebook. Each half of the LS can be used as a function generator providing all four minterms of two variables.

The outputs are active low, hence the outputs that are not addressed are high. Sign up using Email and Password.

The E enable line can be used as active low input.

In the logic diagram of the 74LS, you have exactly that. In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram.

Not more than one output should be shorted at a time, nor for more than 1 second.

Black Mamba 2. I just better understood the concept from you than from Tom’s answer.

Thanks for the answer. SCILLC products are not designed, intended, or authorized for use as components in systems intended for surgical implant into the body, or other applications intended to support or sustain life, or for any other application in which the failure of the SCILLC product could create a situation where personal injury or death may occur. In your first paragraph you say that a demux requires: There is no select lines.

These four minterms are useful in some applications, replacing multiple gate functions as shown in Fig. Home Questions Tags Users Unanswered.

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.

Wouter van Ooijen If yes then how can I give it input and select lines? Thanks for simplifying the answer. What, exactly, do you think the function of pins 1 and 15 are?

Full text of ” IC Datasheet: Post as a 74l139 Name. Here is the link to take a look at datasheet. Each decoder has an active LOW Enable input which can be used as a data input for a 4-output demultiplexer.
