MC74LCX540DW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

MC74LCX540DW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MC74LCX540DW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。

Low-Voltage CMOS Octal Buffer Flow Through Pinout
