Can i use a instead of 74HC?
It should work fine. As Humpawumpa says, invert the logic in your code. It is like the circuit I drew up but has 8 of them in one package. Post as a guest Name. I will check it for sure. What are the differences between and 74HC that you can read out of the datasheet? No need to install a bulky IC. The relay can be from 3. Sparky 11k 2 15 So when I am active high, the led turns on.

74HC540 Octal Inverter Buffer/Line Driver
The Datasheeet consumes little current so is not an issue. So isnt considering an IC the best solution.
I dont understand what this means. Means to actively drive the pin for the inactive state instead of using a separate inverter? Thanks for the answer. This solution works when there is a single relay.
