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

(TOP VIEW)  
To ensure the high-impedance state during power  
up or power down, OE should be tied to V  
CC  
through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking  
capability of the driver.
