Yes, CD4000 may be specified to operate down to 3V...even old CD4000B 20V logic will work down
to 3V (if you like sllooowwww...).
Hi,
I neither know how you come to 22 Ohms...nor do I know how you want to connect it.
In my eyes it makes no sense.

Yes, in this datasheet they call it "leakage" current. In other datasheets the just say "input current".can i ask where did you see, what page was input current of 1uA? input leakage current?
There is a confusion: in the first post there just was the supply_voltage problem of the HCT device.so i guess i should buy HC dmx instead of HCT since my arduino is HC and cs5480 is HC right? for me to save component placement, cost and space on board?
not exactly.so i guess i should buy HC dmx instead of HCT since my arduino is HC and cs5480 is HC right?

Now we addtionally have the 5V (ARDUINO) to 3v3 (CS5480) voltage converson problem.
To solve both in one device you could use the recommended AHC family: --> 74AHC138
yeah, i guess there really is a time where i should consume a lot of time for things like this.In either case you need to read through the datasheets of the devices you use. (We professionals need to do this, too. Booring, but essential)
