SN54/74LS Motorola QUAD 2-INPUT MULTIPLEXER ChipFind Datasheet Archive |

I was browsing for an electronics project and came by to this. Mar 23, 2. Mar 23, 1. Do you already have an account? So are there other bcd to 7 segment ICs that will properly display the hexadecimal output? Need help with circuit Posted by karaandnick in forum: Posted by 1ronman in forum: Two displays, one with one set of seven resistors, two transistors as digit drivers. Whenever there is a carry, the LED lights up.


This would drive two digits. The device should not be operated at these limits. Mar 23, 11 0. Mar 24, 9.


Search the history of over billion web pages on the Internet. The way the circuit works is that the computer or microcontroller or Arduino or whatever puts out the BCD values of two numbers, A and B. A 4 bit binary adder circuit. Yes, my password is: What we’ve been doing in school is that our professor dafasheet out a schematic and then we replicate the schematic in EAGLE and 74ls175 create the hardware using pcbs.

Ok so I think I’ll go with this idea. The parametric values defined in the “Electrical Characteristics” table are not guaranteed at the absolute maximum ratings. Life support darasheet 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.

The BCD parts would be perfect if you can find them. Your initial question about how to generate the data select signal indicates that you don’t fully understand how this circuit works, or 74ls1157 it should be used.

Mar 23, 3. Then the controlling system toggles the Data Delect signal. Does it have to be 8 data lines?


A 4-bit word is selected from one of two sources and is routed to the four outputs. Need help with circuit! Then I’ll create a program from Microprocessor using assembly language.

You can do that without the multiplexing circuit shown.

74LS157 Quad 2-Input Multiplexer

Aug 1, 7, 74l157, It is able to display directly from the outputs of ‘ to 0-F in 7 segment format. If you want to display a 2-digit number using data lines out of a microcontroller, there are several ways to do this.

Absolute Maximum Ratings Note Note: Use this tutorial to get your FPGA development environment setup and understand the tool set and basic development process. You can use two 4-bit adders in series to make an 8-bit adder. The schematic still lacks something. I can design a better replacement, but that’s your job.

Your name or email address: Since that option is no longer an option, we move on. The “Recommended Operating Conditions” table will define the conditions for actual device operation.
