To Design and Implement of 4-bit binary Adder using IC 7483.

Written by @
Apparatus required:- The following electronics components are required.
•OR Gate (IC-7432)
•AND Gate (IC-7408)
•EX-OR Gate (IC-7486)
•Digital Trainer KIT
•Connecting wires
A binary adder is a digital circuit that produces the arithmetic sum of two binary numbers. It can be constructed with full adders connected in cascade, with the output carry from each full adder connected to the input carry of next full adder in chain. The augends bits of ‘A’ and the addend bits of ‘B’ are designated by subscript numbers from right to left, with subscript 0 denoting the least significant bits. The carries are connected in chain through the full adder. The input carry to the adder is C0 and it ripples through the full adder to the output carry C4.

Conclusion: - All the output verified the result of Truth Table.
Precaution in lab:-
•All the connections should be tight and proper.
•Handle the ICs carefully.
•Check the connection once again before Switching on the Digital Trainer KIT.
•Switch of the Trainer Kit after performing the Experiment.

    its wrong

  2. good work

  3. Hey there! I know this is kinda off topic but I was wondering if you knew where I could get
    a captcha plugin for my comment form? I'm using the same blog platform as yours and I'm having problems finding one?
    Thanks a lot!

  6. what if i have a 14 pin 7483 ic

  7. in addition 0001 0111 the s2 is 0...or 1 ???

  8. Hi, I believe your truth table for binary adder may be wrong on the last few, but everything else is great!
