M74HC280B1R集成电路（IC）的奇偶校验发生器校验器规格书PDF中文资料

M74HC280B1R属于集成电路（IC）的奇偶校验发生器校验器。由意法半导体集团制造生产的M74HC280B1R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 M54/74HC280 is a high speed CMOS 9-BIT PARITY GENERATOR fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low consumption.
