TLC5946: How should I handle unconnected pins?

Emma Darby

Part Number: TLC5946

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!

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?
