Description
74283 – 4-Bit Binary Full Adder with Fast Carry
📄 **Description:
The 74283** is a high-speed 4-bit binary full adder designed for use in arithmetic logic circuits. It performs addition of two 4-bit binary numbers and a carry input, producing a 4-bit sum and a carry-out. It features fast look-ahead carry logic, enabling high-speed arithmetic operations without the delay associated with ripple-carry adders.
Compatible with TTL logic levels, the 74283 is widely used in ALUs, counters, calculators, and other digital systems where precise and fast binary addition is required.
