DESCRIPTION/ORDERING INFORMATION  
This octal bus transceiver is designed for 1.65-V to  
3.6-V VCC operation.  
The SN74LVC245A 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 effectively are isolated.
