LDC1614-Q1: Could you please tell me how to deal with the pins when not used?

Part Number: LDC1614-Q1


Hello,

My customer would like to know how to deal with the pins when not used.  Would you please tell me about it except power and GND pins?  I checked the datasheet, but it doesn't show the information.

Best Regards,

    Hello,

    The SCL, SDA, and ADDR pins are all required connections. SCL and SDA must have pull-up resistors to the logic high level for the I2C communication to operate. ADDR may be either pulled up or pulled down (depending on the desired I2C address), but may not be allowed to float. 

    The SD, CLKIN, INTB, and INxA/INxB pins are all optional. The SD pin must not be allowed to float. If unused, it should be pulled to ground. If the internal oscillator is used, CLKIN should be tied to ground. INTB may be allowed to float if unused. INxA/INxB may also float if unused, or they may be tied to ground. They will be grounded internally if not used.

    Most of this information may be found in the Pin Functions table on page 4 of the datasheet.

    Best Regards,
