description  
These 25-octal buffers and line drivers are  
designed specifically to improve both the  
performance and density of 3-state memory  
address drivers, clock drivers, and bus-oriented  
receivers and transmitters.

These buffers are capable of sinking 188-mA I  
,
OL  
which facilitates switching 25-transmission  
lines on the incident wave. The distributed V

CC  
and GND pins minimize switching noise for more  
reliable system operation.

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.  
NC – No internal connection  
The SN54BCT25244 is characterized for  
operation over the full military temperature range  
of 55°C to 125°C. The SN74BCT25244 is  
characterized for operation from 0°C to 70°C.
