CD74ACT280M96集成电路（IC）的奇偶校验发生器校验器规格书PDF中文资料

CD74ACT280M96属于集成电路（IC）的奇偶校验发生器校验器。由美国德州仪器公司制造生产的CD74ACT280M96奇偶校验发生器和校验器逻辑奇偶校验发生器和校验器系列器件是元件级器件，用于评估设置为 1 的数字字中的位数，并另外生成（或评估）一个奇偶校验位，指示设置为 1 的字中的位数是偶数还是奇数。此功能通常用作检测在传输过程中可能引入的数据错误的简单方法。

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 (åE output is HIGH) when an even number of

data inputs is HIGH. Odd parity is indicated (åO output is

HIGH) when an odd number of data inputs is HIGH. Parity

checking for words larger than nine bits can be accomplished

by tying the åE output to any input of an additional

’AC280, ’ACT280 parity checker.
