TA = 125°C

(1)

VDD and VSS can be any value as long as 8 V ≤ (VDD – VSS) ≤ 44 V, and the minimum VDD is met.

(2)

Source pin voltage (Sx) under a fault condition may not exceed 85 V from supply pins (VDD and VSS.) or drain pins (D, Dx).

(3)

Logic output pin (FF) is an open drain output and should be pulled up to a voltage within the max ratings

6.5 Electrical Characteristics (Global)

at TA = 25°C (unless otherwise noted)

Typical at VDD = 15 V, VSS = –15 V, GND = 0 V (unless otherwise noted)
