SN74AHC165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

SN74AHC165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SN74AHC165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

The SN74AHC165 device contains an 8-bit serial-in,

parallel-out shift register that feeds an 8-bit D-type

storage register. The storage register has parallel 3-

state outputs. Separate clocks are provided for both

the shift and storage registers. The shift register has

a direct overriding clear (SRCLR) input, a serial (SER)

input, and a serial output for cascading. When the

output-enable (OE) input is high, all outputs except

QH′ are in the high-impedance state.
