description (continued)
When V
CC
is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.5 V, the output-enable (OE
) input should be tied to V
CC
through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of
the driver.
