التطبيقات

  • Arithmetic logic unit (ALU)
  • Address calculation
  • Digital signal processing
  • Binary counter/multiplier building block

The SN74LS283N from Texas Instruments is a 4-bit binary full adder that adds two 4-bit numbers (A0-A3 and B0-B3) plus a carry-in (C0) and produces a 4-bit sum (Σ0-Σ3) plus a carry-out (C4). The internal fast carry lookahead generates the C4 output without waiting for the carry to ripple through all four stages, making the 4-bit addition time only 24ns. For wider additions, the C4 output of one 74283 connects to the C0 input of the next, creating an 8-bit adder with two chips, or a 16-bit adder with four chips. The 74283 is the building block of arithmetic logic units (ALUs) in simple processors and digital signal processing systems. The N suffix denotes the PDIP-16 through-hole package.

The SN74LS283N adds A[3:0] + B[3:0] + C0 and outputs Σ[3:0] + C4. Internally, it uses carry lookahead logic: instead of computing each bit’s carry sequentially (ripple carry), it generates all carries simultaneously using the generate (G) and propagate (P) signals. Gi = Ai AND Bi (stage i generates a carry); Pi = Ai XOR Bi (stage i propagates an incoming carry). The carry at each stage is: Ci+1 = Gi OR (Pi AND Ci). For a 4-bit adder: C1 = G0 + P0·C0, C2 = G1 + P1·G0 + P1·P0·C0, C3 = G2 + P2·G1 + P2·P1·G0 + P2·P1·P0·C0, C4 = G3 + P3·G2 + P3·P2·G1 + P3·P2·P1·G0 + P3·P2·P1·P0·C0. This reduces the carry propagation from 4 gate delays (ripple) to 2 gate delays (lookahead), enabling the 24ns total addition time. The sum at each bit is: Σi = Pi XOR Ci. For subtraction (A−B), complement B and add 1 (set C0=1): A − B = A + NOT(B) + 1.

The 74283 is a 4-Bit Binary Full Adder. Family variants span from the original LS TTL (5V only) to modern LVC/AUP (down to 0.8V). HC and HCT versions offer 2-6V CMOS operation with HCT providing TTL-compatible input thresholds for mixed 5V systems. CD4000-series equivalents offer the widest 3-18V supply range at the cost of lower switching speed. DIP packages (N suffix) are through-hole; SOIC (D suffix) and TSSOP are surface-mount.
