The ’AC245 octal bus transceivers are designed  
for asynchronous two-way communication  
between data buses. The control-function  
implementation minimizes external timing  
requirements.

(TOP VIEW)  
When the output-enable (OE) is low, the device  
passes noninverted data from the A bus to the B  
bus or from the B bus to the A bus, depending on  
the logic level at the direction control (DIR) input.  
A high on OE disables the device so that the buses  
are effectively isolated.
