The TC74AC280F calculates the parity of the nine input bits (A through I). The Σ Even output is high if the number of high inputs is even, indicating even parity. Conversely, the Σ Odd output is high if the number of high inputs is odd, indicating odd parity. By monitoring these outputs, a system can detect whether an error has occurred during data transmission or storage. The device operates within a temperature range of -40°C to +85°C.
