The SN74LS56P is a dual 4-bit binary full adder with fast carry from Texas Instruments. It is a 8-pin dual in-line package (DIP-8) device.
Description: The SN74LS56P is a dual 4-bit binary full adder with fast carry. It has two 4-bit binary full adders with fast carry. Each full adder has two 4-bit binary inputs (A and B) and one carry input (Cin). The two full adders share a common carry output (Cout). The two 4-bit binary outputs (S1 and S2) are the sum of the two 4-bit binary inputs plus the carry input.
