Product Summary

The 74F280D is a high-speed parity generator/checker that ac-cepts nine bits of input data and detects whether an even or an odd number of these inputs is HIGH. If an even number of inputs is HIGH, the Sum Even output is HIGH. If an odd number is HIGH, the Sum Even output is LOW. The Sum Odd output is the complement of the Sum Even output.

Parametrics

74F280D absolute maximum ratings: (1)Storage Temperature: -65℃ to +150℃; (2)Ambient Temperature under Bias: -55℃ to +125℃; (3)Junction Temperature under Bias: -55℃ to +175℃; (4)Plastic: -55℃ to +150℃; (5)VCCPin Potential to Ground Pin: -0.5V to +7.0V; (6)Input Voltage: -0.5V to +7.0V; (7)Input Current: -30 mA to +5.0 mA; (8)Voltage Applied to Output in HIGH State (with VCC-0V), Standard Output: -0.5V to VCC; TRI-STATE Output: 0.5V to +5.5V; (9)Current Applied to Output in LOW State (Max): twice the rated IOL(mA); (10)ESD Last Passing Voltage (Min): 4000V.

Features

74F280D feature: Guaranteed 4000V minimum ESD protection.
