SRC4194 in SW mode should HW select pins be left floating?

Hi,

I'm using the SRC4194 in software mode, but am unsure whether the unused hardware mode select pins should simply be left floating or tied to GND or VDD?

Many Thanks,

Mark

Hi, Mark,

The pin description on page 6 of the d/s shows which pins are disabled while in s/w mode. Look at the footnote, "(1) Disabled in Software control mode."

Thanks Don,

Thought that was the case, just wanted to make sure that those pins could be left unconnected,

Thanks,

Mark
