Can unsued ports (inputs and outputs be left floating)?

Question

Hello, 
 I am using several ADG1634 ICs in my board but in the last one, I only use two ports (S1A/B & D1 and S2A/B & D2). S3/D3 and S4/D4 are unused at all. 
 Is it okay if I leave the S3A/B, S4A/B, D3 and D4 floating? What about IN3 and IN4? 
 Thank you.

Hi emnet, 
 
 You can connect S3A/B, S4A/B via resistors to GND. D3 and D4 can be left floating or also connect them via resistors to GND. IN3 and IN4 can float.
