description
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 (...
