Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

 


Description

These 25-W octal buffers and line drivers of SN54BCT25244 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 of SN54BCT25244 are capable of sinking 188-mA_OL I ,which facilitates switching 25-W 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 SN54BCT25244 transmits data from the A inputs to the Y outputs. When 1OE and 2OE are high, the outputs are in the high-impedance state.


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.
