MC10H645集成电路（IC）的时钟缓冲器驱动器规格书PDF中文资料

MC10H645属于集成电路（IC）的时钟缓冲器驱动器。由安森美半导体公司制造生产的MC10H645时钟缓冲器，驱动器时钟缓冲器和驱动器集成电路产品族中的产品用于帮助信号在系统中传输，常用作频率/时间参考信号，以同步系统内的活动。尽管这些器件最常用到的功能就是缓冲（即，为使信号不受驱动负载的影响而从某个信号源复制信号），但是该产品族中的某些器件还能执行其他功能，例如选择性改变缓冲信号路径、按某个整数值分割信号频率，或进行所用电信号格式转换。

描述 Description

The MC10H645 is a single supply, low skew, TTL I/O 1:9 Clock Driver. Devices in the H600 clock driver family utilizes the PLCC−28 for optimal power and signal pin placement.

The device features a 24 mA TTL output stage with AC performance specified into a 50 pF load capacitance. A 2:1 input Mux is provided on chip to allow for distributing both system and diagnostic clock signals or designing clock redundancy into a system. With the SEL input held LOW the DO input will be selected, while the D1 input is selected when the SEL input is forced HIGH.
