[sdiy] So what's the difference between these IC's?

Absolute Max Vdd
CD4030 - Max 15V
CD4070 - Max 18V

Some manufacturers just do the 4070.

>And the same applies to the CD4016 versus the CD4066 they're both quad

Different internal structure here - more fets in the 4066 to start with. As
already stated, about 1/4 of the on resistance. 80 ohms versus 300 at 15V
