These octal bus transceivers are designed for asynchronous two-way 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 on the logic level at the direction-
control (DIR) input. The output-enable () input can be used to disable the device so the buses are effectively isolated.

The SN54ALS1245A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS1245A is characterized for operation from 0°C to 70°C.
