MC14008B
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
Pin–for–Pin Replacement for CD4008B
