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 transmis-

sion 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.
