74HC241D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

74HC241D属于集成电路（IC）的缓冲器驱动器接收器收发器。由安世半导体(中国)有限公司制造生产的74HC241D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。

1. General description

The 74HC241; 74HCT241 is an 8-bit buffer/line driver with 3-state outputs. The device can be used

as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE),

each controlling four of the 3-state outputs. A HIGH on 1OE or LOW on 2OE causes the associated

outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use

of current limiting resistors to interface inputs to voltages in excess of VCC.

The 74HCT241 device features reduced input threshold levels to allow interfacing to TTL logic

levels.
