SN74CBTLV3125: I2C Clock Stretching Consult

Part Number: SN74CBTLV3125

Hi Team,

Customer feedbacks that the I2C frequency is pulled down from 62.5kHz to 41.6kHz through our SN74CBTLV3125. Does this device has clock stretching functions inside?



  • No, this device is a passive analog switch. It cannot reduce the frequency.

    The switch will add a little bit of resistance and capacitance to the line, but a digital 62.5 kHz signal should not be affected by this.
