High-Speed CMOS Logic  
4-Bit Binary Full Adder with Fast Carry  
November 1997 - Revised October 2003  
Features  
Description  
• Adds Two Binary Numbers  
The ’HC283 and ’HCT283 binary full adders add two 4-bit  
binary numbers and generate a carry-out bit if the sum  
exceeds 15.  
• Full Internal Lookahead

• Fast Ripple Carry for Economical Expansion  
• Operates with Both Positive and Negative Logic  
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.  
• Fanout (Over Temperature Range)
