Control of outputs of MC33882 output switch

[ondrej_brejla]

Hi,

I´m planning on using the MC33882 for realisation of digital outputs on a project I´m working on. I'm going to use the SPI interface to control the outputs. It's not really clear to me what should I do with the remaining input pins (IN0...IN7 and IN0&IN1 … IN4&IN5). Is it better to connect them to GND or just leave them with their internal pull down? Also should the unused outputs be left unconnected ?

Best regards,

Hi,

For IN you can connect them to GND,for outputs you can floating.

Thanks!
