FAST AND LS TTL DATA
4-BIT BINARY FULL ADDER
WITH FAST CARRY
The SN54/74LS83A is a high-speed 4-Bit binary Full Adder with internal
carry lookahead. It accepts two 4-bit binary words (A1–A4, B1–B4) and a
Carry Input (C0). It generates the binary Sum outputs
∑
1–
∑
4) and the Carry
Output (C4) from the most significant bit. The LS83A operates with either
active HIGH or active LOW operands (positive or negative logic). The
SN54/74LS283 is recommended for new designs since it is identical in
function with this device and features standard corner power pins.
