4-Bit Binary Fill Adder With Fast Carry
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.
