description
This octal bus transceiver is designed for
asynchronous
communication
between
data
buses. The devices transmit data 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 be used to disable the device
so the buses are effectively isolated.
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 SN64BCT245 is characterized for operation from 40
°C to 85°C and 0°C to 70°C.
