description  
The SN64BCT25244 is a 25-octal buffer and line driver designed specifically to improve both the performance  
and density of 3-state memory address drivers, clock drivers, and bus-oriented transceivers.  
When the output-enable (1OE and 2OE) inputs are low, the device transmits data from the A inputs to the  
Y outputs. When 1OE and 2OE are high, the outputs are in the high-impedance state.  
This buffer/driver 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 value is  
less than approximately 3 V.  
The SN64BCT25244 is characterized for operation from 40°C to 85°C and 0°C to 70°C.
