The q denotes specifications which apply over the full specified
temperature range.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: With all four VID inputs floating, the VCC supply current is simply
the device leakage current. However, the VCC supply current will rise and
be approximately equal to the number of grounded VID input pins times
(VCC – 0.6V)/40k. (See the Typical Applications section for more detail.)
Note 3: Each built-in pull-up resistor attached to the VID inputs also has a
series diode connected to VCC to allow input voltages higher than the VCC
supply without damage or clamping. (See Operation section for further
detail.)
