74AHC273BQ: 带复位功能的八频D型触发器;正沿触发器

74AHC273;74AHCT273是高速硅栅CMOS器件并且与低功耗肖特基TTL(LSTTL)引脚兼容。它符合JEDEC标准No. 7-A。

74AHC273;74AHCT273具有带单独D输入和Q输出的八个边沿触发D类触发器。

通用时钟(CP)和主复位(MR)同时输入、加载和复位(清零)所有触发器。

在时钟从低到高转换前的某个建立时间,每个D输入状态都会被传输到相应的触发器输出(Qn)。

通过MR输入上的低电平,所有输出都会被强制为不受时钟或数据输入影响的低电平。

该器件对于仅需要真正输出,并且时钟和主复位常用于所有存储元件的应用非常有用。
