Description
The SN74LS82 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 an 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.
