We need a Level shifter, that from 1.8V CMOS to 3.3V CMOS;
Total need 6 channels, if you recommend 2 channels, we will use 3pcs each set.
I found CD4555BPWR, but it may not be most suitable.

Can you help recommend other one?

Thanks

CD4000 is a high-voltage family and does not support 1.8 V. (And the CD4555B is not a level shifter.)

You could use a single eight-channel device like the SN74AXC8T245, or combine four and two channels with the SN74AXC4T245 and SN74AXC2T45.
