CD74HC280
高速 CMOS 逻辑 9 位奇偶校验发生器/校验器
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 E output to any input of an additional HC/HCT280 parity checker.
