74LVT245BB  
3.3 V OCTAL BUS TRANSCEIVER WITH 3 STATE OUTPUTS  
Description  
Pin Assignments  
The 74LVT245BB is an octal transceiver 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) Pin can be used to disable the device so the buses effectively  
are isolated.

The inputs are tolerant to 5.5V allowing this device to be used in a  
mixed voltage environment. The device is fully specified for partial  
power down applications using IOFF. The IOFF circuitry disables the  
output preventing damaging current backflow when the device is  
powered down.
