Hi;

Still working on the analog switch issue here. I'm thinking of using a
MAX4661 to replace a relay in a switching unit. The relay switches 15v from
float to ground (at 0.15mA). I've been reading the data sheet:

http://datasheets.maxim-ic.com/en/ds/MAX4661-MAX4663.pdf

and on p.7 it talks about power supply sequencing. I'm new to these devices,
so I just want to make sure I understand what they mean. In my application,
it is very likely that the 15v that I need to switch will hit the COM or NC
before the device is powered up. Is this the situation they are advising be
avoided? If so, why would this potentially damage the device?

Thanks
