description/ordering information  
These octal bus transceivers are designed for asynchronous two-way communication between data buses. The  
control-function implementation minimizes external timing requirements.  
The ’AHCT245 devices allow data transmission 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. The output-enable (OE) input can be used to  
disable the device so that the buses effectively are isolated.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
