Description

The MC14008B 4bit full adder is constructed with MOS Pchannel and Nchannel enhancement mode devices in a single monolithic structure. MC14008B consists of four full adders with fast internal lookahead carry output. It is useful in binary addition and other arithmetic applications. The fast parallel carry output bit allows highspeed operation when used with other adders in a system.
