Hi Team,
Customer using TCA9539-Q1, the I2C bus also connected 10 other devices like temp sensors. But other devices' leakage current are very small (uA level)
From datasheet page 18, SLVA689, the min pull up resistor is 967 ohm. But in real test, they have to use 2.2k ohm resistor. Lower resistor value will cause bit error.
The total I2C bus length is around 40cm, Could you help why the resistor can't be as low as in SLVA689?
Thank you!
Marc
