description  
These octal bus transceivers are designed for asynchronous communication between data buses. These  
devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the level at  
the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the  
buses are effectively isolated.  
The 74AC11643 is characterized for operation from 40°C to 85°C.
