Note 1. The maximum junction temperature of the NTE1509 is +100
°
C. Device must be derated for
operation at elevated temperatures. Junction to ambient thermal resistance is 55
°
C/W.
Note 2. Pin5 input current must be limited to
±
3mA. The addition of a 39k
resistor in series with
Pin5 allows
±
100V signals without damage.
