My solution is to use P channel mosfets to switch the power. Datasheet using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Email Required, but never shown.

You are not wrong.

Maybe you will be OK afterall, or maybe a simple part change can fix everything up. I’m loosing some voltage 4. A simple indicator LED will be fine at 5 mA. I have no control over end devices. It would have been so simple to use a current drain driver but sadly it’s not an option.

Data sheet is here: You should make sure that the design actually tries to do that. Hi, basic schematic added.

Glad to know i’m not going nuts. 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.

The IC datasheet a global limit of 70 mA. The datasheft is between the IC and ground source current? Sign up using Email and Password.

And that supply current is also the main part of the current that datazheet outputs. Get on to your supplier and ask them to justify their thoughts.

There is a ready made solution and the supplier insists datashet will be OK but having read the data sheet I don’t think it will. Would really appreciate 74hc5t73n input. Nik Middleton 6 5. My belief is that turning on all 8 outputs at 20 ma exceeds the IC max current.


My understanding is that is has a max of 35 mA per pin, but a total of 70 mA for the IC. This website has a built-in schematic editor. However, driving a LED at 20 mA is often unnecessary today. Sign up using Facebook. 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. Post as a guest Name. It’s not always LED’s but they are non inductive.

I’ve been reading a lot 74ht573n data sheets of late looking for chips that will work for a small project.
