These 10-bit bus transceivers are designed for  
asynchronous two-way communication between  
data buses. The control function implementation  
allows for maximum flexibility in timing.

GAB  
These devices allow data transmission from the A  
bus to the B bus or from the B bus to the A bus  
depending upon the logic levels at the enable  
inputs (GBA and GAB).

(TOP VIEW)  
The enable inputs can be used to disable the  
device so that the buses are effectively isolated.
