I need an analog multiplexer that I can use with a 3.3v NodeMCU. Someone suggested the CD4051. I am just checking to make sure this works with 3.3v? Thanks!

IIRC 4000 series CMOS chips can be used with any Vcc from 3 VDC to 18 VDC subject to an adjustment in timing specifications. The chips are faster at higher values of Vcc.. As always -- pay particular attentions to the footnotes in the datasheet.
