Hello all,
I have a pretty basic question concerning Fairchild's H11L1. I am using it as isolation and also to step up a switching voltage from 5V to 12V or 24V for a drive circuit. The output of the H11L1 will only be turning on an NPN BJT(2N3904) which should require less than a milliamp and a 10K resistor to ground which will only pull a few milliamps. Under "Safety and Insulation Ratings" in the datasheet it claims Ps is 800mW. But, under "Maximum Ratings" in the datasheet it claims the output can only range from 0-16V. Since I am only drawing a few milliamps at the output, can I use 24V for Vcc as long as I stay below 800mW? Or does the higher potential on the collector cause problems over time?
Thanks in advance!
