3.2. Recommended Operating Conditions
www.DataSheet4U.com
Do not insert the device into a live socket. Instead, apply power by switching on the external power supply.
Keep UVDD=AVDD during all power-up and power-down sequences.
Failure to comply with the above recommendations will result in unpredictable behavior of the device and may result in device
destruction.
Functional operation of the device beyond those indicated in the “Recommended Operating Conditions” of this specification is not
implied, may result in unpredictable behavior of the device and may reduce reliability and lifetime.
Table 3–2: All voltages listed are referenced to ground (UVSS=HVSSn=AVSS=0V), except where noted. All grounds except VSS
must be connected externally low-ohmic.
