TLC5946: How should I handle unconnected pins?

Hi,

I am not using XERR, SOUT, XHALF, EPAD, and two constant sink current OUT pins. What should I do with all of those pins? Leave them floating or connect to ground?

Thanks!

Emma

    Hi Emma,

    XERR and OUTx are open-drain outputs. SOUT is shift register output. You could leave them floating.

    XHALF need to be pulled high to set the device in normal operation, if you do not use the extended serial interface.

    What is EPAD you mentioned?
