Notes:
5. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted
together.
6. 3,750 VACRMS for 1 minute duration is equivalent to 4,500 VACRMS for 1 second duration.
Electrical Characteristics (Apply over all recommended conditions, typical value is measured at
VDD1 = VDD2 = +3.3V, VDD1 = +3.3V and VDD2 = +5.0V, VDD1 = +5.0V and VDD2 = +3.3V, VDD1 = VDD2 = +5.0V, TA = 25°C)
