Hi Team,

I am using the few TI voltage translators in my design.

I am attaching the schematic pdf and layout or board file of the same.

Please go through it and let me know your inputs.

With regards,

Hi,

Taking a look at your schematic and I've noticed the following things:

R822 is unnecessary. OE is a normal CMOS input and is high impedance. You can DNP R822 if R893 is DNP'ed as well.
DNP C730 and instead populate C727. See this video for more information on this:

I also see that you might plan on driving the EN pin in the future. I would highly recommend watching the below video to learn how to do that:
- https://training.ti.com/using-enable-pin-lsf-family?cu=1134826
Overall, the circuit for the LSF0102 looks good, however I would be sure to reference all of the links in section 12.1 of the datasheet to ensure that your design fits your end application.

Thanks!

Hey Jayashree,

It looks like the only IC included on the schematic you sent was U89 (the LSF0102DCTR).

My only recommendation for this IC is that you follow the guides listed in section 11 of the datasheet. It seems that for this device you have, and all looks good.

Thanks!
