74LVX244MTR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

74LVX244MTR属于集成电路（IC）的缓冲器驱动器接收器收发器。由意法半导体集团制造生产的74LVX244MTR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。

DESCRIPTION

The 74LVX244 is a low voltage CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power, battery operated and low noise 3.3V applications.
