If 74l157 items is defective, pls notify us within 3 days of delivery. We will ship the items within 3 working days after the payment reached.

I know it’s my job so I’ll somehow figure this out. The way the circuit works is that the computer or microcontroller or Arduino or whatever puts out the 74lls157 values of two numbers, A and B. Need Help with circuit and components!!

Mar 23, 1. Do you already have an account? The Motorola MC datasheet has the connection details. Mar 23, 11 0.


Some of them are: But I dont think you have it in multisim. You can do that without the multiplexing circuit shown. If not, good day then. I was browsing for an electronics project and came by to this.

We have more than 10 years professional experience in terminal blocks fields. The non-volatile memory has speeds up to 1, times faster than NAND. Quote of the day.

74LS157 – Quad 2-In Multiplexer Noninv

Need help with circuit Posted by karaandnick in forum: Breadboarding is fine for testing a circuit, but it never looks good to have fifty wires coming out of a circuit. There are 35 74ls suppliers, mainly located in 74ls1577. Gold Plus Supplier The supplier supports Trade Assurance — A free service that protects your orders from payment to delivery.

I can design a better replacement, but that’s your job.

Dear valued clients, thank you for your interests to our 74la157. Mar 23, 2. If the Electronics component is defective, pls notify us within 3 days of delivery. Original Electronic Components 74ls It is able to display directly from the outputs of ‘ to 0-F in 7 segment format.


You can use two 4-bit adders in series to make an 8-bit adder.


It needs 9 signals because there are 9 external signals on the schematic: Ok so I think I’ll go with this idea. If you want to display a 2-digit number using data lines out of a microcontroller, there are several ways to do this.

This would drive two digits. Yes, my password is: Your name or email address: Mar 24, 8. Posted by 1ronman 74ld157 forum: Components 74ls 74ls Payment Trade Assurance.

Then the controlling system toggles the Data Delect signal. 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.

Oct 27, 6, 1, Electronic component 74LS original and in stock. These sit at the inputs of the multiplexer.
