Notes:
1. Absolute maximum ratings are limits beyond which
operation may cause permanent damage to the device.
These are stress ratings only; functional operation at or
above these limits is not implied.
2. When the input voltage (VIN) at any pin exceeds the
power supplies (VIN < GND or VIN > VDD), the current at
that pin should be limited to 5mA. The 20mA maximum
package input current rating limits the number of pins
that can safely exceed the power supplies with an input
current of 5mA to four. Parasitic components and/or
ESD protection circuitry are present on the aSC7611
pins. Care should be taken not to forward bias the
parasitic diode present on pins D+ and D-. Doing so by
more than 50mV may corrupt temperature
measurements.
