Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated underRecommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The pin voltage is clamped by an internal circuit, and is not specified to have an external voltage applied.
STATUS can go below ground during the STATUS low-to-high transition. The negative voltage on STATUS during this transition is clamped by an internal diode and it does not damage the device.
High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.
