Full text of ” IC Datasheet: Home Questions Tags Users Unanswered. In your first paragraph you say that a demux requires: I just better understood the concept from you than from Tom’s answer. VIEWP n nr 0.
The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs. 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.
Sign up or log in Sign up using Google. Each half of the LS generates all four minterms of two variables. Your explanation resolved my confusion. Black Mamba 2. Each half of the LS can be used as a function generator providing all four minterms of two variables.
All operating parameters, including “Typicals” must be validated for each customer application by customer’s technical experts. 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. So, I compared it to Demux’s Enable input. Not more than one output should be shorted at a time, nor for more than 1 second.
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. 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.
These four minterms are useful in some applications, replacing multiple gate functions as shown in Fig.
There is no select lines. Post as a dafasheet Name. The outputs are active low, hence the outputs that are not addressed are high.
Thanks for the answer. In the logic diagram of the 74LS, you have exactly that.

If yes then how can I give it input and select lines? In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram. Email Required, but 74ks139 shown. Wouter van Ooijen Each decoder has an active LOW Enable input which can be used as a data input for a 4-output demultiplexer.

SCILLC makes no warranty, representation or guarantee regarding datssheet 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.
Thanks for simplifying the answer. So, I was confused. Here is the link to take a look at datasheet.
