P82B715: clock speed and power dissipation

Part Number: P82B715

Hi Experts,
Good day! Could you help me to provide information for P82B715DR that is not found on the datasheet?
1. what is clock speed?
2. what is power dissipation?
Thank you in advance for your support.
Best regards,
Jonathan
  • 1. The P82B715 does not have an internal clock. Its propagation delay allows signals up to 400 kHz.

    2. Its quiescent supply current is specified in section 6.5 of the datasheet. You probably want to add the power dissipated in the pull-up resistors.

  • Hi Jonathan,

    1. what is clock speed?

    Clemens is correct here. This device does not output a clock speed but instead receives a clock input from the I2C bus. This device allows up to 400 kHz clock signal from the SCL line of the I2C bus. 

    2. what is power dissipation?

    I agree with Clemens. Highest current consumption occurs when both buffered inputs are driven LOW.  Typical is 22 mA through ICC when this happens. You can use this estimate along with VCC, and the power dissipated through the pull-up resistors on both sides of the device in order to calculate an estimate for the total power dissipated through the device. 

    Regards,
