OCTAL BUS TRANSCEIVERS  
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 transmis-  
sion 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.
