描述 Description

The SN64BCT25245 is a 25- octal bus transceiver designed for asynchronous communication between data buses. It improves both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented transceivers.
The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the direction-control (DIR) input. The output-enable () input can disable the device so that both buses are effectively isolated.
This transceiver 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 is less than approximately 3 V.
The SN64BCT25245 is characterized for operation from -40°C to 85°C and 0°C to 70°C.
