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.
