SN74ABT646ADBR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

SN74ABT646ADBR属于集成电路（IC）的缓冲器驱动器接收器收发器。由美国德州仪器公司制造生产的SN74ABT646ADBR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/ordering information

These devices consist of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed

transmission of data directly from the input bus or from the internal registers. Data on the A or B bus is clocked

into the registers on the low-to-high transition of the appropriate clock (CLKAB or CLKBA) input. Figure 1

illustrates the four fundamental bus-management functions that can be performed with the ’ABT646A devices.
