Part Number: TLC5973

(1) Can you confirm if the SDI pin for TLC5973 can be connected to host controller GPIO pin directly?

(2) Does it need any pullups?

(3) Does it need to connect to specific 1-wire interface controller?

Hi Summer,

I am the original enquirer regarding this part.

I am only planning to use 2 LEDs to be driven by this IC? Is it OK to leave OUT2 unconnected?

There will be total of 2 part count of TLC5973DR, driving 5 LEDs in total.

Best regards,

TeeHowe
