Part Number: TCA9517-Q1

Hi team,

Good day.

What is the I2C rise and fall time of CLOCK and DATA signals for TCA9517-Q1?


Regards,
Carlo

  • Hey Carlo,

    The rise time is dependent on the bus loading as I2C's rise is based on the RC constant where R is the pull up resistance and C is the parasitic bus capacitance. The fall time is based on the same principal however the TCA9517 can drive low with its NFET which you can calculate the Ron based on the IoL and VoL on A side.
