Octal Bus Transceivers
These octal bus transceivers are designed for asynchronous
two-way communication between data buses. Control function
implementation minimizes external timing requirements. These
circuits allow data transmission from the A bus to B or from the B bus
to A bus depending upon the logic level of the direction control (DIR)
input. Enable input (G) can disable the device so that the buses are
effectively isolated.
