Hi Team,
Customer see the SDA(IN) and SDA(OUT) is latched with voltage level 1.4V and no SCL signal after buffer(TCA4311A) is enabled about 1minute. (Vcc is 3.3V)
Can you help review the TCA4311A schematic and provide your comment? I suggest customer to change the pull high to 10k as datasheet.
Thanks,
SHH
