Hello all, I see the max current per I/O pin is 40mA. I'm wishing to drive a SCR that is spec'd at 35mA gate trigger. Since the SCR will be triggered all the time to conduct, 35mA seems a bit close to the max for comfort.
Is it possible to parallel 2 or 3 I/O pins and them share the load? OR is an interfacing transistor on order? Sure would like to parallel I/O pins if that will work. Timing is not critical, I'm using the SCR to turn voltage on for power supply, then if an alarm condition is detected, remove trigger to remove voltage from output of power supply.
Thank ya'll for any help and suggestions.
