74LS157 – Quad 2-In Multiplexer Noninv

And how can I make this display 2 digit outputs? Two displays, one with one set of seven resistors, two transistors as digit drivers. This would drive two digits.

The Motorola MC datasheet has the connection details. Your initial question about how to generate the data select signal indicates that you don’t fully datasheer how this circuit works, or why it should be used.

I 1 0. Then the controlling system toggles the Data Delect signal.

Yes, my password is: Then I’ll create a program from Microprocessor using assembly language. Quote of the day. Whenever there datashheet a carry, the LED lights up. The device should not be operated at these limits. I was browsing for an electronics project and came by to this.

The BCD parts would be perfect if you can find them. The “Recommended Operating Conditions” table will define the conditions for actual device operation. I can design dayasheet better replacement, but that’s your job.

What we’ve been doing in school is that our professor gives out a schematic and then we replicate the schematic in EAGLE and then create the hardware using pcbs. Mar 24, A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness. Mar 23, 7. Mar 25, Do you already have an account?

You can do that without the multiplexing circuit shown. Mar 23, 5. After 9, the 7 segment doesn’t display A,B,C,etc. Need help with circuit Posted by karaandnick in forum: Mar 24, 9.

Not sure if you have it in your sim Use this tutorial to get your FPGA development environment setup and understand the tool set and basic development process. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain datasheeet, 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.

Your name or email address: Oct 27, 6, 1, Not more than one output should be shorted at a time, and the duration should not exceed one second.

Just so you guys know, I have literally zero knowledge in creating my own schematics. Mar 23, 2.

Note that the circuit you linked actually needs 9 signals to operate, and is overly complex in my opinion. Given that the two number values are static at the multiplexer input, the circuit is overly complex. Once you understand how this one “works” and what is wrong with it, that will guide an alternative design. You can move part of the multiplexing task to your software and use only 6 signals from the uC.
