High-Speed CMOS Logic

9-Bit Odd/Even Parity Generator/Checker

November 1997 - Revised October 2003

Features

Description

• Typical Propagation Delay = 17ns at V

= 5V,

The ’HC280 and ’HCT280 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.

C = 15pF, T = 25 C
