SN74HCT244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

SN74HCT244属于集成电路（IC）的缓冲器驱动器接收器收发器。由德州仪器制造生产的SN74HCT244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。

3 Description

These octal buffers and line drivers are designed

specifically to improve both the performance

and density of 3-state memory address drivers,

clockdrivers, and bus-oriented receivers and

transmitters. The SNx4HCT244 devices are organized

as two 4-bit buffers or drivers with separate outputenable

(OE) inputs. When OE is low, the device

passes noninverted data from the A inputs to the Y

outputs. When OE is high, the outputs are in the highimpedance

state.
