Hi Shifali,

Can you confirm if the HPD signal itself is open drain? If so, the TXS0104E (includes internal pullups, so external pullups not needed) or LSF0204 (external pullups required) would work better here.

Please provide additional system considerations to help narrow down recommendation.

Regards,

Jack

Hi Jack,

Whether TXB,TXS and LSF are footprint and pin-pin compatible with each other?

Thanks,

Hi Shifali,

Yes, TXB0104, TXS0104E, and LSF0204 in RUT package are all P2P, though note that the TXB0104 will not support open drain signals.

Hi Jack,

I'm currently using TXB0102DCUR level transltor in my design. Can you suggest any alternate footprint compatible level translator that suports open drain signals.

Thanks,

Hi Shifali,

The TXS0102DCUR would be able to support this application.
