Full text of ” IC Datasheet: Not more than 74ls19 output should be shorted at a time, nor for more than 1 second. The E enable line can be used as active low input.

Your explanation resolved my confusion. The outputs 74ls1399 active low, hence the outputs that are not addressed are high. 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 adtasheet 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.

774ls139 I just better understood the concept from you than from Tom’s answer. 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 74l1s39 special, consequential or incidental damages.

These four minterms are useful in some applications, replacing multiple gate functions as shown in Fig. Each half of the LS generates all four minterms of two variables. Thanks for the answer.

Post as a guest Name. 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. There is no select lines. 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.

So, I was confused. Post Your Answer Discard By clicking “Post Your Answer”, 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.

After that I have taken a look at the datasheet of 1: In your first paragraph you say that a demux requires: The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs. VIEWP n nr 0.

Each decoder has an active LOW Enable input which can be used as a data input for a 4-output demultiplexer. What, exactly, do you think the function of pins 1 and 15 are?

Black Mamba 2. Thanks for simplifying the answer. Here is the link to take a look at datasheet. So I will accept it.

All operating parameters, including “Typicals” must be validated for each customer application by customer’s technical daatsheet. In fact the image you show from the datasheet explains this in the “Pin Names” section just below the connection diagram. Email Required, but never shown. If yes then how can I give it input and select lines? Should Buyer purchase or 74ls319 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 datawheet manufacture of the part.

So, I compared it to Demux’s Enable input. Home Questions Tags Users Unanswered. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and dtaasheet policyand that your continued use of the website is subject to these policies.

In the logic diagram of the 74LS, you have exactly that.
