description

The SN64BCT25245 is a 25-Ω 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 (OE) 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-Ω 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.
