Description

The CD54AC283/3A and CD54ACT283/3A are 4-bit binary
adders with fast carry that utilize the Harris Advanced CMOS
Logic technology. These devices add two 4-bit binary num­bers and generate a carry-out 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.

The CD54AC283/3A and CD54ACT283/3A are supplied in
16 lead dual-in-line ceramic packages (F suffix).
