74LS139 – Dual 1-of-4 Dcdr Demultiplexer
Search the history of over billion web pages on the Internet. VIEWP n nr 0. Each half of the LS generates all four minterms of two variables. If yes then how can I give it input and select lines?
Your explanation resolved my confusion. So, I was confused. In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram.
In your first paragraph you say datasheeet a demux requires: The outputs are active low, hence the outputs that are not addressed are high. Full text of ” IC Datasheet: Thanks for the answer.
The E enable line can be used as datsaheet low input. Sign up using Facebook.

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 744ls139 limitation special, consequential or incidental damages.
Not more than one output should be shorted at a time, nor for more than 1 second. Each decoder has an active 7l4s139 Enable input which can be used as a data input for a 4-output demultiplexer.
Black Mamba 2. Email Required, but never shown. What, exactly, do you think the function of pins 1 and 15 are?

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 datsheet or manufacture of the part.
Each half of the LS can be used as a function generator providing all four minterms of two variables. Post as a guest Name. The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs. Home Questions Tags Users Unanswered.
SCILLC products are not designed, intended, or authorized for use as components ddatasheet 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 simplifying the answer.
Wouter van Ooijen 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.

Sign up 74ls39 log in Sign up using Google. So I will accept it. 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.
There is no select lines.
