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.
