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.
Look–Ahead Carry Output
Diode Protection on All Inputs
All Outputs Buffered
Supply Voltage Range = 3.0 Vdc to 18 Vdc
Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range

SUM OUTPUTS
Calculation of 16–bit adder speed:
tP total = tP (Sum to Carry) + tP (Carry to Sum) + 2 tP (Carry to Carry)
The guaranteed 16–bit adder speed at 10 V, 25°C, CL = 50 pF is:
tp total = 290 + 310 + 300 = 900 ns
