Texas Instruments SN74LS280

these universal monolithic 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 application. the word-length capability is easily expanded by cascading as shown under typical application data. series 54ls/74ls and series 54s/74s parity generators/checkers offer the designer a trade-off between reduced power consumption and high performance. these devices can be used to upgrade the performance of most systems utilizing the 180 parity generator/checker. although the ls280 and s280 are implemented without expander inputs the corresponding function is provided by the availability of an input at pin 4 and the absence of any internal connection at pin 3. view all in datasheet
