CD74AC280数据手册集成电路（IC）的奇偶校验发生器校验器规格书PDF

描述 Description

The ’AC280 and ’ACT280 are 9-bit odd/even parity generator/checkers that utilize Advanced CMOS Logic technology. 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 ’AC280, ’ACT280 parity checker.
