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).
Features
• Outputs Source/Sink 24 mA
• HD74ACT283 has TTL-Cmpatible Inputs
• Ordering Information: Ex. HD74AC283
