4.6.1.1. Recommended Operating Conditions
Functional operation of the device beyond those indicated in the “Recommended Operating Conditions/Characteris-
tics” is not implied and may result in unpredictable behavior, reduce reliability and lifetime of the device.
All voltages listed are referenced to ground (V
V
V
= 0 V) except where noted.
SUP1, SUP2, SUP3
All GND pins must be connected to a low-resistive ground plane close to the IC.
Do not insert the device into a live socket. Instead, apply power by switching on the external power supply. For
power up/down sequences, see the instructions in section Section 2.11.2. of this document.
