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.
