It’s not always LED’s but they are non inductive. The load is between the IC and ground source current? Get on to your supplier and ask them to justify their thoughts. Datashret up using Facebook.

You can edit your question and then click on the icon that looks like a schematic symbol, and it will load the schematic editor. Post as a guest Name. And that supply current is also the main part of the current that datashet outputs. Email Required, but never shown.
My solution is to use P channel mosfets to switch the power. Data sheet is here: This website has a built-in schematic editor. I should have added that there are 2 LEDS being driven from each output. Q are 8 outputs and attach to equipment that requires 20 ma. I’ve been reading a lot of data sheets of late looking for chips that will work for a small project.
Would really appreciate some input. Home Questions Tags Users Unanswered. There is a ready made solution and the supplier insists it will be OK but having read the data sheet I don’t think it will. Glad to know i’m not going 74hcy573n. I’m loosing some voltage 4. It would have been so simple to use a current drain driver but sadly it’s not an option.
Adtasheet understanding is that is has a max of 35 mA per pin, but a total of 70 mA for the IC. Maybe you will be OK afterall, or maybe a simple part change can fix everything up.
