The MC74AC/ACT652 consists of registered bus transceiver circuits, with outputs, D−type flip−flops and control circuitry providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Data on the A or B bus will be loaded into the respective registers on the LOW−to−HIGH transition of the appropriate clock pin (CAB or CBA). The four fundamental data handling functions available are illustrated in Figures 1 to 4.

Features

• Independent Registers for A and B Buses

• Multiplexed Real−Time and Stored Data Transfers

• 3−State Outputs

• 300 mil Slim Dual−in−Line Package

• Outputs Source/Sink 24 mA

• ′ACT652 Has TTL Compatible Inputs

• These are Pb−Free Devices

MC74ACT652DW属于集成电路（IC） > 缓冲器，驱动器，接收器，收发器。安森美半导体公司制造生产的MC74ACT652DW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。
