Team,

Customer wants to know how much current the devcie can sink.

Being used in a control box and they want to put a watchdog timer in it. Testing for that purpose.

Thanks,

Source and sink current would be Ioh and Iol. This is the guarranteed amout of current the part will drive and meet Voh and Vol. It will actually drive more.
