DESCRIPTION/ORDERING INFORMATION  
This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation.  
The SN74ALVC245 is designed for asynchronous communication between data buses. The device transmits  
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. The output-enable (OE) input can be used to disable the device so the buses are  
effectively isolated.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
