multipile MC14051B with single dataline
« on: August 30, 2019, 02:20:21 pm »
Hi all
I want to use 6 MC14051B with ATMEGA328P for upcoming project. but I am not sure how to connect those to the same data line. in another word, I want all 6 ICs connected to same digital pin (for example PB5).
any guid to do such thing ?
I am learning here btw

regards

Have all the outputs connect to that one data line, have all the A/B/C signals in parallel back to the micro, and then a separate inhibit signal to each chip to select which one you want active.

so, when inhibit is set to high, it will be HI-Z mode
right?
