The ’HC283 and ’HCT283 binary full adders add two 4-bit binary numbers and generate a carry-out bit if the sum exceeds 15. This device can be used with either all active-high operands (positive logic) or with all active-low operands (negative logic).
The document describes the CD54HC283, CD74HC283, CD54HCT283, and CD74HCT283 devices, which are high-speed CMOS logic 4-bit binary full adders. These chips add two 4-bit binary numbers and generate a carry-out bit if the sum exceeds 15. They feature internal lookahead carry generation for fast ripple carry expansion.
