DESCRIPTION

The 4008B is a 4-Bit Binary Full Adder with two 4-bit Data Input (A0-A3, B0-B3); a Carry Input (C0), four Sum Output (S0-S3) and a Carry Output(C4).

The 4008B uses full lookahead across 4-bits to generate the Carry Output (C4). This minimizes the necessity for extensive lookahead and carry-cascading circuits.

● CARRY LOOKAHEAD BUFFERED OUTPUT

● EASILY CASCADED
