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 IOL, which facilitates switching 25- transmission lines on the
incident wave. The distributed VCC and GND pins minimize switching noise for more reliable system operation.
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.
