CD54/74AC283, CD54/74ACT283 Data sheet acquired from Harris Semiconductor SCHS251D 4-Bit Binary Fill Adder With Fast Carry August 1998 - Revised May 2000 Features Description • Buffered Inputs 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. • Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 • SCR-Latchup-Resistant CMOS Process and Circuit Design 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. • 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 Ordering Information • ±24mA Output Drive Current - Fanout to 15 FAST™ ICs - Drives 50Ω Transmission Lines PART NUMBER TEMP.
