These octal bus transceivers are designed for asynchronous  
two-way communication between data buses. Control function  
implementation minimizes external timing requirements. These  
circuits allow data transmission from the A bus to B or from the B bus  
to A bus depending upon the logic level of the direction control (DIR)  
input. Enable input (G) can disable the device so that the buses are  
effectively isolated.
