MC14008B

4-Bit Full Adder

The MC14008B 4–bit full adder is constructed with MOS

P–channel and N–channel enhancement mode devices in a single

monolithic structure. This device consists of four full adders with fast

internal look–ahead carry output. It is useful in binary addition and

other arithmetic applications. The fast parallel carry output bit allows

high–speed operation when used with other adders in a system.

This device contains protection circuitry to guard against damage due to high

static voltages or electric fields. However, precautions must be taken to avoid

applications of any voltage higher than maximum rated voltages to this

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
