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 ………………………………………………………….……………………-40C to +85C
PowerCap …………………………………………………………………………-55C to +125C
Lead Temperature (soldering, 10 seconds) ……………………………………………………… +260C
Note: EDIP is wave or hand-soldered only.
