[sdiy] CD405x series power supply question

[The Old Crow]

   Hey folks, Crow here.  The specs for the 4052 state an supply voltage 
range of 20V for Vee=Vss=0V, and 18V for Vee=-Vdd using split dual 
supplies (+/-9V).  I have a case where I need to bias the Vee down about 
1V, creating a 16V supply interval.  While I think this is safe, I have 
blown these parts up before with supply voltage games and wanted to ask 
if anyone has tinkered with small negative values for Vee on the 
4051/4052/4053.  I usually use the DG508/509 for this sort of thing, but 
those parts are 8 times as pricey as a 4052 and I am using 2 of them on 
a project as part of two VC ADSR circuits.
