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 carry-
out 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
