4-BIT BINARY FULL ADDER WITH FAST CARRY
The 74LS83 is a 4-bit binary full adder logic chip from Texas Instruments. It is a 16-pin DIP (dual in-line package) and has two 4-bit inputs (A and B) and one 4-bit output (C), and also includes two carry inputs (C0 and C1) and one carry output (C4). This device can be used in 4-bit addition operations, producing a sum output C and a carry output C4. Features: - Low-power Schottky TTL (LSTTL) compatible inputs and outputs - Internal carry look-ahead capability - Outputs are open-drain - High noise immunity - Chip complexity: 14 equivalents Applications: - 4-bit arithmetic operations - Bipolar/CMOS interface - Analog-to-digital converters - Multiplexers - Adders/subtractors - Binary comparators
