SN74HC652DW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

SN74HC652DW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SN74HC652DW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

The ’HC652 devices consist of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for

multiplexed transmission of data directly from the data bus or from the internal storage registers. Output-enable

(OEAB and OEBA) inputs are provided to control the transceiver functions. Select-control (SAB and SBA) inputs

are provided to select real-time or stored-data transfer. A low input level selects real-time data, and a high input

level selects stored data. Figure 1 illustrates the four fundamental bus-management functions that can be

performed with these devices.
