Note 1

For operation at elevated temperatures the device must be derated based on a 125 C maximum junction temperature and a thermal resistance of 80 CW

(DIP) 120 CW (SO-14) junction to ambient

Note 2

Temporary excursions to 150 C can be tolerated

Note 3

Measured at input to external 18 kX resistor IC contains 1 kX in series with a diode to attenuate the input signal
