ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground………………………………………………………..……..-0.3V to +6.0V
Operating Temperature Range…………………………………………………………………………..……-40°C to +85°C
Storage Temperature Range………………………………………………………………………………...-55°C to +125°C
Lead Temperature (soldering, 10s) ……….………………………………………………………………………. +260°C
Soldering Temperature (reflow) ……………………………………………………………………………………. +260°C
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 in the operational sections of the specifications is
not implied. Exposure to the absolute maximum rating conditions for extended periods may affect device reliability.
RECOMMENDED DC OPERATING CONDITIONS
(VCC = VCC(MIN) to VCC(MAX), TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C, unless
otherwise noted.) (Note 1)
