1 / 12 page 1 Data sheet acquired from Harris Semiconductor SCHS251D Features • Buffered Inputs • Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 • SCR-Latchup-Resistant CMOS Process and Circuit Design • Speed of Bipolar FAST™/AS/S with Significantly Reduced Power Consumption • Balanced Propagation Delays • AC Types Feature 1.5V to 5.5V Operation and Balanced Noise Immunity at 30% of the Supply • ±24mA Output Drive Current - Fanout to 15 FAST™ ICs - Drives 50 Ω Transmission Lines 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 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.
