Octal 25-Ohm Buffer/Driver With 3-State Outputs - SN64BCT25244


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 (1 and 2) inputs are low, the device transmits data from the A inputs to the Y outputs. When 1 and 2 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.
