5.6.3. Re<strong>com</strong>mended Operating Conditions<br />
Functional operation of the device beyond those indicated in the “Re<strong>com</strong>mended Operating Conditions/Characteristics”<br />
is not implied and may result in unpredictable behavior, reduce reliability and lifetime of the device.<br />
All voltages listed are referenced to ground except where noted.<br />
All GND pins must be connected to a low-resistive ground plane close to the IC.<br />
Do not insert the device into a live socket. Instead, apply power by switching on the external power supply.<br />
