74ABT543数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

General Description
The ABT543 octal transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate Latch Enable and Output Enable inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow.

特性 Features

■ Back-to-back registers for storage
■ Bidirectional data path
■ A and B outputs have current sourcing capability of 32
   mA and current sinking capability of 64 mA
■ Separate controls for data flow in each direction
■ Guaranteed output skew
■ Guaranteed multiple output switching specifications
■ Output switching specified for both 50 pF and 250 pF loads
■ Guaranteed simultaneous switching noise level and
   dynamic threshold performance
■ Guaranteed latchup protection
■ High impedance glitch free bus loading during entire
   power up and power down cycle
■ Nondestructive hot insertion capability

简介

74ABT543属于集成电路（IC）的缓冲器驱动器接收器收发器。由制造生产的74ABT543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。
