Operation

The device is ideal for driving bus lines or buffering memory address registers.

This device features inputs and outputs on opposite sides of the package to facilitate printed circuit board layout.

The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output enable (OE1 or OE2)

input is high, all eight outputs are in the high-impedance state.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in

a mixed 3.3-V/5-V system environment.

preventing damaging current backflow through the device when it is powered down.

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