This is a stress only rating and operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. 2. The input and output negative voltage ratings may be exceeded if the inpu t and output diode current ratings are observed. 3. Control input must be held high or Low, it must not float.
