Since you're doing a new design, let me point out the ADuM6422A. The ADuM6422A is the latest generation of isoPower dc/dc converter and meets CISPR 32/EN550 32 Class B emission limits up to 5 Mbps at a full load on a 2-layer PCB
For the ADuM5402, unused inputs can be tied low to keep the related outputs from toggling. The unused outputs are left floating.
