The MC14008B 4-bit full adder is constructed using MOS P-channel and N-channel enhancement mode devices in a monolithic structure. The device includes four full adders with fast internal carry-lookahead outputs. It is used for binary addition and other arithmetic applications. The fast parallel carry-out bit enables high-speed operations when used with other adders in the system.

The MC74AC157/74ACT157 is a high-speed quad 2-input multiplexer. Four bits of data from two sources can be selected using the common select and enable inputs. Four outputs present selected data in true (non-inverted) form. The MC74AC157/74ACT157 can also be used as a function generator.
