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.  
10  
11  
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.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in  
a mixed 3.3-V/5-V system environment.  
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,  
preventing damaging current backflow through the device when it is powered down.
