description  
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 upon  
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.  
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.  
The SN74BCT2245 is characterized for operation from 0°C to 70°C.
