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.
The device features full internal look-ahead
across all four bits generating the carry term C4 in
typically 5.7 ns. This capability provides the
system designer with partial look-ahead
performance at the economy and reduced
package count of a ripple-carry implementation.
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.
