Hi,

Yes.

Page4, table2, last entry: VDD 3/30V Min/max

Note that the signal must remain within the supply rails so should be within 0 to 3.5V for a single 3.5V supply.

There's "work" and there's "work". I'd expect you will
see a large variation in on-resistance and prop delay
(especially at temperature corners) and the part may
be functional but not as good parametric-performance-
wise as you'd think from the front page "highlight reel".
Dig into some of the graphs at the back and pay some
attention to the called-out test conditions of the
datasheet, and be sure you're happy with the real
answer found in the fine print.

I would expect that a switch designed specifically
for low voltage, would be better than one that has
to cover 3-30V (entailing high voltage, big junction
MOSFETs and probably much more channel capacitance
than one designed closer to the bone in a low voltage
CMOS technology. On the other hand the HV device
is probably more robust to some classes of fault. If
you care, which is a question to ask early on.
