FOD8001 — High Noise Immunity, 3.3V/5V Logic Gate Optocoupler
Isolation Characteristics
(Apply over all recommended conditions, typical value is measured at T
A
= 25°C)
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 VAC
RMS
for 1 minute duration is equivalent to 4,500 VAC
RMS
for 1 second duration.
