74AHC(T)574: 八频D型触发器；正边沿触发器；三态

74AHC574；74AHCT574是高速硅栅CMOS器件并且与低功耗肖特基TTL（LSTTL）引脚兼容。它们符合JEDEC标准No. 7A。

74AHC574；74AHCT574是八路D类触发器，具有用于每个触发器的独立D类输入以及用于总线应用的三态输出。时钟（CP）和输出使能（OE）输入常用于所有触发器。

八个触发器会存储它们各自的D输入状态，满足CP从低到高转换的建立和保持时间要求。

OE为低电平时，八个触发器的内容在输出处可用。OE为高电平时，输出会进入高阻抗关断状态。OE输入的操作不会影响触发器的状态。

74AHC574；74AHCT574在功能上等同于74AHC564；74AHCT564具有非反相输出。74AHC574；74AHCT574在功能上等同于74AHC374；74AHCT374具有不同的引脚排列。
