Note 1: For operation at elevated temperatures, the device must be derated based on a 125℃ maximum junction temperature

and a thermal resistance of 80℃/W (DIP), 120℃/W (SO-14) junction to ambient.

Note 2: Temporary excursions to 150℃ can be tolerated.

Note 3: Measured at input to external 18kΩ resistor. IC contains 1kΩ in series with a diode to attenuate the input signal.
