The SN74LVCR16245A is designed for asynchronous communication between data buses. The
control-function implementation minimizes external-timing requirements.
This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission 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 (OE) input can disable the device so that the buses are effectively isolated.
