Shuhei Goto

Part Number: PCA9546A

Tool/software:

Hi team,

Is the input rise time longer than 1000ns no problem if the signal meet these requirements?

  • I2C serial-data setup time
  • I2C serial-data hold time
  • I2C clock high time
  • I2C clock low time

Best regards,
Goto

    Hello Goto,

    A rise time longer than 1000ns exceeds the recommended operation conditions and can affect the operation of the device. 

    Going beyond what is recommended can cause unpredicted behaviors with the device. 

    Thanks,

    Nir
