Notes:
1. Insulation characteristics are guaranteed only within the safety maximum ratings, which must be ensured by protective circuits within the
application.
2. Safety-limiting parameters are dependent on ambient temperature. The Input Current, IS,INPUT, derates linearly above 25°C free-air temperature at
a rate of 2.53 mA/°C; the Output Power, PS,OUTPUT, derates linearly above 25°C free-air temperature at a rate of 4 mW/°C.
