DESCRIPTION
The UT54ACS280 and the UT54ACTS280 are 9-bit parity generators/checkers that use high-performance circuitry and features odd and even outputs to facilitate operation of either odd
or even parity application. The word-length capability is easily
expanded by cascading.
The devices are characterized over full military temperature
range of -55 C to +125 C.
