the act16623 are 16-bit transceivers designed for asynchronous two-way communication between data buses. the control-function implementation allows for maximum flexibility in timing. these devices can be used as two 8-bit transceivers or one 16-bit transceiver. they allow 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 output-enable ( and oeab) inputs. the output-enable inputs can be used to disable the device so that the buses are effectively isolated. the dual-enable configuration gives the bus transceiver the capability to store data by simultaneously enabling and oeab. each output reinforces its input in this transceiver configuration. view all in datasheet
