SN74LS652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

SN74LS652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SN74LS652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

These 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. Enable GAB and GBA are

provided to control the transceiver functions. SAB and

SBA control pins are provided to select whether realtime

or stored data is transferred. A low input level selects

real-time data, and a high selects stored data. The

following examples demonstrate the four fundamental

bus-management functions that can be performed with

the 'LS651, 'LS652, and 'LS653.
