stg
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under
is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to V
SS
, unless otherwise noted.
Continuous clamp current per pin is ±2 mA. This includes the analog inputs which have an internal clamping circuit that clamps the
voltage to a diode drop above V
DDA2
or below V
SSA2
.
One or both of the following conditions may result in a reduction of overall device life:
• long-term high-temperature storage
• extended use at maximum temperature
