74LS139 Datasheet PDF
All operating parameters, including “Typicals” must be validated for each customer application by customer’s technical experts. The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs.

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. After that I have taken a look at the datasheet of 1: The E enable line can be used as active low input.
Each half of the LS generates all four minterms of two variables. These four minterms are useful in some applications, replacing multiple gate functions as shown in Fig. SCILLC makes no warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does SCILLC assume any liability arising out of the application or use of any product or circuit, and specifically disclaims any and all liability, including without limitation special, consequential or incidental damages.

If yes then how can I give it input and select lines? In your first paragraph you say that a demux requires: Sign up using Facebook. In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram. In the logic diagram of the 74LS, you have exactly that. Each decoder has an active LOW Enable input which can be used as a data input for a 4-output demultiplexer.
So, I compared it to Demux’s Enable input. The outputs are active low, hence the outputs that are not addressed are high. Here is the link to take a look at datasheet. Should Buyer purchase or use SCILLC products for any such unintended or unauthorized application, Buyer shall indemnify and hold SCILLC and its officers, employees, subsidiaries, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that SCILLC was negligent regarding the design or manufacture of the part.
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.
Thanks for the answer. Each half of the LS can be used as a function generator providing all four minterms of two variables. Not more than one output should be shorted at a time, nor for more than 1 second.

VIEWP n nr 0. There is no select lines. I just better understood the concept from you than from Tom’s answer. Datasgeet for simplifying the answer.
