Description

The SN74LS280N is a 9-bit odd/even Parity Generator/Checker utilizes 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. It offers the designer a trade-OFF between reduced power consumption and high performance. It can be used to upgrade the performance of most systems utilizing the "180 parity generator/checker. Although It is 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.
Generates either odd or even parity for nine data lines
Cascadable for n-bits
Can be used to upgrade existing systems using MSI parity circuits
