Your explanation resolved my confusion. In the logic diagram of the 74LS, you have exactly that. The device has two independent decoders, each of which accept two binary weighted inputs AAi and provide darasheet mutually exclusive active LOW outputs O0-O3.

Thanks for simplifying the answer. Home Questions Tags Users Unanswered.

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

What, exactly, do you think the function of pins 1 and 15 are? The outputs are active low, hence the outputs that are not addressed are high.

Thanks for the answer. Each decoder has an active LOW Enable input which can be used as a data input for a 4-output demultiplexer. Here is the link to take a look at datasheet. Sign up or log in Sign up using Google.

VIEWP n nr 0. 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.

Full text of ” IC Datasheet: Not more than one output should be shorted at a time, nor for more than 1 second. Sign up using Email and Password. So I will accept it. The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs. Dtasheet your first paragraph you say that a demux requires: Each half of the LS generates all four minterms of two variables. I just better understood the concept from you than from Tom’s answer.

Wouter van Ooijen There is no select lines. Each half of the LS can be used as a function generator providing all four minterms of two variables. After that I have taken a look at the datasheet of 1: If yes then how can I give it input and select lines?
