  • See the application report CMOS Power Consumption and Cpd Calculation (SCAA035). But the datasheet does not specify Cpd.

  • In reply to Clemens Ladisch:

    Yeah We tried calculating the Cpd using the application note,  but it came in negative. I have attached an document below.POWER_BUFFER with cpd.xls

    Hi,

    Can you please help me with this power consumption, i have also attached an excel document with regarding to this.

    Hi Jivesh,

    The Icc in you spreadsheet seems a little too low. Are these measured results?

    Check out our new AXC family of Voltage Translators! 

    Watch the Introduction to AXC Family to find out more about the family.

  • In reply to Dylan Hubbard:

     No they are not the measured results.I got the Icc data from the datasheet of SN74LVTH16543DGGR (page no. 6).

    Hi Jivesh,

    The datasheet says .19 mA not uA. Also this is a bench measurement so you would need to test the device to back calculate Cpd.
