Description

The HD74AC283/HD74ACT283 high-speed 4-bit binary full adder with internal carry lookahead accepts two 4-bit binary works (A0 A3, B0 B3) and a Carry input (C0). It generates the binary Sum outputs (S0 S3) and the Carry output (C4) from the most significant bit. The HD74AC283/HD74ACT283 will operate with either active High or active Low operands (positive or negative logic).
