DESCRIPTION
The UT54ACS283 and the UT54ACTS283 are 4-bit binary ad-
ders. The adders perform 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 devices are characterized over full military temperature
range of -55°C to +125°C.
