74F623 OCTAL BUS TRANSCEIVERS

These octal bus transceivers are designed for asynchronous 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 (OEAB and OEBA) inputs. The output-enab.
