The UT54ACS283E is a 4-bit binary full adder. The adder per-
forms addition of two 4-bit binary words. The sum () outputs
are provided for each bit and the resultant carry (C4) is obtained
as the fifth bit. The adders feature full internal look-ahead across
all four bits for fast carry generation.
The device is characterized over full military temperature range
of -55C to +125C.

Note:
Input conditions at A1, A2, B1, B2, and C0 are used to determine outputs
1
and
2
and the value of the internal carry C2. The values at C2, A3, B3, A4, and B4 are
then used to determine outputs3,
4,
and C4.
