description/ordering information  
GND  
The SN74BCT2245 octal transceiver and line/  
MOS driver is designed for asynchronous  
communication between data buses.  
The 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 disable the devices so that  
both buses are effectively isolated.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The B-port outputs, which are designed to source or sink up to 12 mA, include 33-Ω series resistors to reduce  
overshoot and undershoot.
