MC74VHCT244ADW集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

MC74VHCT244ADW属于集成电路（IC）的缓冲器驱动器接收器收发器。由安森美半导体公司制造生产的MC74VHCT244ADW缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。

The MC74VHCT244A is an advanced high speed CMOS octal bus buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
