Half & Full Subtractor Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12733
Indian Lab Suppliers supplies the Half & Full Subtractor Trainer (Product ID: 12733) as part of its electronics engineering lab equipment range. It verifies the truth tables of a half subtractor (two inputs) and a full subtractor (with borrow input) built from standard TTL gates.
Quick Answer
A half subtractor gives difference D = A EX-OR B and borrow = (NOT A) AND B; the full subtractor adds a borrow-in and combines two such stages with an OR gate. On this board the circuits use AND (7408), NOT (7404), OR (7432) and EX-OR (7486) gate ICs. Three SPDT switches set the inputs low or high and four LEDs show the outputs. A 5 V DC, 100 mA regulated supply is built in and the unit runs from 230 V ±10%, 50 Hz mains. It weighs about 1 kg.
