LTC6957 - OK to Drive inputs While Part is Unpowered?

Hi, 

For the various types of LTC6957 devices, is it ok to drive the inputs (with a signal level of appropriate swing that would be the same as what would be applied when the part is on) while the LTC6957 device itself is unpowered (V+ and VDD do not have any voltage applied yet)? I am considering if special care needs to be taken with turn on sequencing in this regard. Based on image of input stage below it seems to me like it should be OK but I would like to confirm. For the inputs I only see absolute max current ratings specified, not any max voltage rating such as "-0.3V to VDD" which I often see in datasheets to indicate input pins should never be driven above supply voltage (which they would be if driven while part unpowered so VDD=0V). Thanks. If this information is actually in the datasheet and I just missed it please do let me know...
