These quadruple bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation allows for maximum flexibility in timing. These devices allow data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic levels at the output-enable (OEBA and ) 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 quadruple bus transceivers the capability to store data by simultaneously enabling OEBA and . Each output reinforces its input in this transceiver configuration. When both control inputs are enabled and all other data sources to the two sets of bus lines are at high impedance, both sets of bus lines (eight in all) retain their states
