So I will accept it. By clicking “Post Your 74lz139, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Here is the link to take a look at datasheet. Sign up using Email and Password. Black Mamba 2. These four minterms are useful in some applications, replacing multiple datassheet functions as shown in Fig. What, exactly, do you think the function of pins 1 and 15 are? Thanks for simplifying the answer.

74LS Datasheet pdf – Decoder/Demultiplexer – Fairchild Semiconductor

I just better understood the concept from you than from Tom’s answer. Each decoder has an active LOW Enable input which can be used as a data input for a 4-output demultiplexer. In your first paragraph you say that a demux requires: Thanks for the answer. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. In the logic diagram of the 74LS, ratasheet have exactly that. Each half of the LS generates all four minterms of two variables.


VIEWP n nr 0. 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 7ls139 any product or circuit, and specifically disclaims any and all liability, including without limitation special, consequential or incidental damages.

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? The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs. Home Questions Tags Users Unanswered.

Your explanation resolved my confusion. The E enable line can be used as active low input.


Full text of ” IC Datasheet: There is no select lines. So, I was confused. So, I compared it to Demux’s Enable input.

Wouter van Ooijen Sign up or log in Sign up using Google. Search the history of over billion web pages on the Internet. Each half of the LS can be used as a function generator providing all four minterms of two variables.

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. Not more than one output should be shorted at a time, nor for more than 1 second. Sign up using Facebook. The outputs are active low, hence the outputs that are not addressed are high. 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.

After that I have taken a look at the datasheet of 1: SCILLC products are not designed, intended, or authorized for use as components in systems intended dstasheet surgical implant into the body, or other applications intended dataheet 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.

All operating parameters, including “Typicals” must be dataseet for each customer application by customer’s technical experts. Email Required, but never shown.
