Part Number: LSF0108-Q1

Hi team,

For LSF0108-Q1, it seems that there is no spec of VIL/VOL in datasheet. Is there any reason not having the spce?

Can you let me know the spec for each voltage?

Thanks,

Sam Lee

Hi Sam,
I would highly recommend watching this video series to understand how the LSF family of translators works: training.ti.com/TLM-LSF-Intro

I think that will also answer your question.

Hi Sam Lee,

Please refer to the app note on the factors which affect the Vol of the LSF device.

The Vol is directly proportional to the Vil + the IR drop across the pass FET of the device. The LSF is a passive translation device and not a true buffer and hence the VIH / VIL specs of the buffers wont apply.

Do you know the application use case? What are the interfaces, data rate and any other information you could provide
