LM393B: Can I connect 1.8V Pull up to the output Pin?

Anush Balraj1

Part Number: LM393B
Other Parts Discussed in Thread: LM393-N, LM393

Tool/software:

Iam using LM393M/NOPB in my design. As part of some change i want to connect the output to FPGA IO pin at 1.8V.

So please can you confirm if i can connect 1.8V pull up on the output of the comparator. I think it should work. But please confirm.

Also please share the Pspice model for simulation if available.

Yes, the output can be pulled up to any voltage between 0 V and 36 V.

For the PSpice model, on the product page, click "Design & development" / "Design tools & simulation".

Thanks for the information.

There is no Pspice model in "Design & development" / "Design tools & simulation".

Sorry; I was looking at the LM393B page.

The LM393 and LM393-N are clones of each other; you can use the LM393 model.
