DM74S280 9-Bit Parity Generator/Checker
General Description
These universal, nine-bit parity generators/checkers utilize
Schottky-clamped TTL high-performance circuitry, and feature odd/even outputs to facilitate operation of either odd or even parity applications.
The word-length capability is easily expanded by cascading.
The DM74S280 can be used to upgrade the performance of most systems utilizing the DM74180 parity generator/ checker.
Although the DM74S280 is implemented without expander inputs, the corresponding function is provided by the availability of all input at pin 4, and no internal connection at pin 3.
