Hi,

In the attached schematics for review, I have used TXB0102 level translator for CEC. Is that acceptable. Since CEC is open drain shouldn't I be using TXS0102 level translator.

The TXB indeed does not work with open-drain signals. You must use the TXS0102 or the LSF0102.

No, AVC translators use push/pull buffers.
