Verification of Excess-3 to Decimal Converter Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12740
Indian Lab Suppliers supplies the Verification of Excess-3 to Decimal Converter (Product ID: 12740) as part of its electronics engineering lab equipment range. It verifies the conversion of excess-3 coded inputs into decimal digits.
Quick Answer
Excess-3 code represents each decimal digit as its BCD value plus 3 (0 is 0011, 9 is 1100). On this board, gate logic converts the excess-3 input set on SPDT switches back to BCD, and a BCD-to-decimal decoder IC then lights the matching decimal output on the LEDs. It carries two quad 2-input NAND ICs, a hex inverter, two triple 3-input NAND ICs and the decoder IC, with a built-in 5 V DC, 100 mA regulated supply and patch cords with 4 mm plugs. It runs from 230 V ±10%, 50 Hz mains.
