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. 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.

If yes then how can I give it input and select lines? So, I compared it to Demux’s Enable input.

The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs. Thanks for simplifying the answer.

So I will accept it. SCILLC products are not designed, intended, or authorized for use as components in systems intended for dataxheet 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.

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. The outputs are active low, hence the outputs that are not addressed are high.

I just better understood the concept dqtasheet you than from Tom’s answer. Post as a guest Name.
