description/ordering information  
A4  
A5  
The SN74AHC245 octal bus transceiver is designed  
for asynchronous two-way communication between  
data buses. The control-function implementation  
minimizes external timing requirements.  
A6  
A7  
A8  
GND  
This device allows 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  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
