LM393 to LM319 for driving FET's.

[ACharnley]

Quick one, at the moment I'm driving FET's using 10k pull up/down resistors. The circuit is working perfectly.

I'd like to eliminate these and use the LM319, however I was expecting the output to pull up and it does not. It could be an issue with my model?

Any advice appreciated!

Look at the datasheet:

The LM319 has open collector outputs, so it needs a pull-up resistor.

Drat, can you or anyone suggest a comparator with an active pullup?

TLV7211 is one.
