2 Description

The ’AC283 and ’ACT283 4-bit binary adders with fast

carry that utilize Advanced CMOS Logic technology.

These devices add two 4-bit binary numbers and

generate a carryout bit if the sum exceeds 15.

Because of the symmetry of the add function, this

device can be used with either all active-HIGH

operands (positive logic) or with all active-LOW

operands (negative logic). When using positive logic,

the carry-in input must be tied LOW if there is no

carry-in.
