description  
The SN64BCT25245 is a 25-octal bus transceiver designed for asynchronous communication between data  
buses. It improves both the performance and density of 3-state memory address drivers, clock drivers, and  
bus-oriented transceivers.  
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 device so that  
both buses are effectively isolated.  
This transceiver is capable of sinking 188-mA I , which facilitates switching 25-transmission lines on the  
OL  
incident wave. The distributed V  
and GND pins minimize switching noise for more reliable system operation.  
CC  
The outputs are in a high-impedance state during power up and power down while the supply voltage is less  
than approximately 3 V.  
The SN64BCT25245 is characterized for operation from 40°C to 85°C and 0°C to 70°C.
