The NTE7482 is a 2-bit binary full adder in a 14-lead DIP-type package that performs the addition of two 2-bit binary numbers. The sum outputs are provided for each bit and the resultant carry (C2) is obtained from the second bit. Designed for medium to high-speed, multiple-bit, parallel-add/serial-carry applications, this circuit utilizes high-speed, high-fan-out transistor-transistor logic (TTL) and is compatible with both DTL and TTL logic families. The implementation of a single-inversion, high-speed, Darlington-connected serial carry circuit within each bit minimizes the necessity for extensive "look-ahead" and carry cascading circuits.
