Jusar As is stated in the below table the output max current is 35mA for each output, being the nominal current 20mA, enough to control a LED in every output.

You are not wrong. Sign up or log in Sign up using Google. Post as a guest Name. The load is between the IC and ground source current? Q are 8 outputs and attach to equipment that requires 20 ma. You should make sure that the design actually tries to do that. A simple indicator LED will be fine at 5 mA.

My solution is to use P channel mosfets to switch the power. I should have added that there are 2 LEDS being driven from each output.

However, driving a Datsaheet at 20 mA is often unnecessary today. Would really appreciate some input. And that supply current is also the main part of the current that feeds outputs. This website has a built-in schematic editor.

Hi, basic schematic added. Email Required, but never shown. Get on to your supplier and ask them to justify their thoughts. I have no control over end devices. Sign up using Email and Password. My 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.
