Description

The Harris CD74HC280 and CD74HCT280 are 9-bit

odd/even parity, generator checker devices. Both even and

odd parity outputs are available for checking or generating

parity for words up to nine bits long. Even parity is indicated

(ΣE output is high) when an even number of data inputs is

high. Odd parity is indicated (ΣO output is high) when an odd

number of data inputs is high. Parity checking for words larger

than 9 bits can be accomplished by tying the ΣE output to any

input of an additional HC/HCT280 parity checker.

• Wide Operating Temperature Range . . . -55 C to 125 C

• Balanced Propagation Delay and Transition Times
