description

These octal bus transceivers are designed for asynchronous communication between data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction-control (DIR) input. The output-enable input can be used to disable the device so that the buses are effectively isolated.

The 74AC11640 is characterized for operation from -40°C to 85°C.
