M74HC85B1R集成电路（IC）的比较器规格书PDF中文资料

M74HC85B1R属于集成电路（IC）的比较器。由意法半导体集团制造生产的M74HC85B1R比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。

DESCRIPTION

The M74HC85 is an high speed CMOS 4-BIT MAGNITUDE COMPARATOR fabricated with silicon gate C2MOS technology.
