| Description | OCTAL BUS TRANSCEIVERS |
|
|
These octal bus transceivers are designed for asynchronous two-way munication between open-collector and 3-state buses. The devices transmit data from the A bus (open-collector) to the B bus (3 state) or from the B bus to the A bus, depending on 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 isolated.
