Hello

TXS0102 has internal pull up register 10kohm.

Is the precision of this resistance ± several percent?

Customer use between CEC of DS90UH929 and SoC.

It is necessary for the pulling up resistance of CEC to use the resistance of 27kΩ +-10%.

Best Regards,

The internal pull-up resistor variation is about +-15%. When TXS0102 is on disable, the I/O is at hihg-Z status. I think it is better to add external pull-up resistor on CEC signal.

Thanks
