operation, but with the capability to provide a TTL interface to a 5-V system environment.

These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission

from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control

(DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively

isolated.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
