Difference between ADUM1301 and ADUM1311 - Pinout same?

Hi 

I believe the main differences  are speed and, resulted from that, power. 
ADUM1301 is up to 90Mbps, whereas ADUM1311 is up to 10Mbps.

Are there any other significant differences?
The pin out is the same so far seen.

That means new parts like ADUM131E1 will be also compatible with ADUM1311.
Correct?
