SN54F283 Overview
Description
The ′F283 is a full adder that performs the addition of two 4-bit binary words. The sum (Σ) outputs are provided for each bit and the resultant carry (C4) output is obtained from the fourth bit.
Key Features
- full internal look-ahead across all four bits generating the carry term C4 in typically 5.7 ns
- The adder logic, including the carry, is implemented in its true form
- End-around carry can be accomplished without the need for logic or level inversion
- The ′F283 can be used with either all-active-high (positive logic) or all-active-low (negative logic) operands
- The SN54F283 is characterized for operation over the full military temperature range of - 55°C to 125°C
- The SN74F283 is characterized for operation from 0°C to 70°C
