Datasheet «SN54/74LS157»

So are there other bcd to 7 segment ICs that will properly display the hexadecimal output? Your name or email address: I probably need to use the 8 data pins of a parallel cable and to create the respective program in assembly language. The BCD parts would be perfect if you can find them. I know it’s my job so I’ll somehow figure this out. Posted by Raptor in forum: Your initial question about how to generate the data select signal indicates that you don’t fully understand how this circuit works, or why it should be used.


Need help with circuit — 74ls decoder and 74ls multiplexer. | All About Circuits

Given that the two number values are static at the multiplexer input, the circuit is overly complex. Mar 23, 6.

The “Recommended Operating Conditions” table will define the conditions for actual device operation. Mar 25, Once you understand how this one “works” and what is wrong with it, that will guide an alternative design. Quote of the day. Mar 23, 3.

Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and whose failure to perform, when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user. Not sure if you have it in your sim Ice 74,s157 measured with 4. Mar 24, 8. Do you have any more ideas that could use 8 data lines?


Then I’ll create a program from Microprocessor using assembly language. Just so you guys know, I have literally zero knowledge in creating my own schematics. The Motorola MC datasheet has the connection details. I can design a better replacement, but that’s your job. No, create an account now.

This would drive two digits. Some of them are: Full text of ” IC Datasheet: Mar 23, 11 0. Two displays, two decoders each with 7 resistors8 data lines four to eachand you’re done.

After 9, the 7 segment doesn’t display A,B,C,etc. A separate strobe input is provided.

Mar 23, 4. Mar 23, 1. Whenever there is a carry, the LED lights up.
