I've got some TTP223-BA6 soldered to some self-designed PCBs. My question is about the datasheet and the IC, respectively. How much current can I get through this little IC before it get's destroyed? Mostly I find something like "absolute maximum ratings". In this case, there is no "absolute maximum rating" für sink/source current but voltage. Maybe I lack the knowledge to derive it from the specs? On page 3 there is just
Output Port Sink Current IOL VDD=3V, VOL=0.6V - 8 - mA Output Port Source Current IOH VDD=3V, VOH=2.4V - -4 - mA
. And do I understand correctly, that output port source current means "pin is high"?
Would be great if someone could help me improve my datasheet reading skills.
Thanks & best
