ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground (5V product) ………………………..-0.3V to +6.0V
(3.3V product) ……………………..-0.3V to +4.6V
Storage Temperature Range
EDIP ………………………………………………………….……………………-40ºC to +85ºC
PowerCap …………………………………………………………………………-55ºC to +125ºC
Lead Temperature (soldering, 10 seconds) ……………………………………………………… +260ºC
Note: EDIP is wave or hand-soldered only.
Soldering Temperature (reflow, PowerCap) …………………………………………………… +260ºC
This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operation
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time can affect
reliability.
