74LCX240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

74LCX240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74LCX240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 74LCX240 is a low voltage CMOS OCTAL BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs. It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption.
