Product Code : SCL-EELE-12732
Indian Lab Suppliers supplies the 4 Bit Binary Full Adder & Subtractor (Product ID: 12732) as part of its electronics engineering lab equipment range. It adds and subtracts two 4-bit binary numbers with a 4-bit full adder IC and EX-OR controlled inverters.
Quick Answer
The EX-OR gates act as controlled inverters: with the mode control at 0 the second number passes unchanged and the full adder IC adds; at 1 it is inverted and, with a carry-in of 1, the circuit subtracts by 2’s complement. SPDT switches set the two 4-bit numbers and mode, and LEDs show the result. Built-in parts are a 4-bit full adder IC, a quad 2-input EX-OR gate IC and a 5 V DC, 200 mA regulated supply; the board runs from 230 V ±10%, 50 Hz mains.
