Other Parts Discussed in Thread: CD40109B-Q1,
I was previously using PN# CD40109BQNSRQ1 to level shift from 12v to 3.3v. I needed extra inputs so changed to PN#CD4010BQDRQ1. I am currently running vehicle turn signals through it to send 3.3v to microcontroller. With the new chip I can disconnect power from the board, but leave turn signals on and the board stays powered through the level shifter. The old part did NOT do this. Is there something I'm missing or just chose wrong chip, and if so do you have recommendation? This is how each chip is pinned out.
