0 °C to 70 °C
-40 °C to 125 °C
0.3 to 7 Volts
Note: Stresses above those listed under Absolute Maximum
Rating may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these
or any other conditions above those indicated in the operational
section of the specifications is not implied. Exposure to abso-
lute maximum rating conditions for extended periods may
affect product reliability.
Standard Test Conditions
The characteristics below apply for the following standard test
conditions, unless otherwise noted. All voltages are referenced
to VSS (OV Ground). Positive current flows into the referenced
pin.
