First of all, I'd like to say I'm new here... Not just to this board but to programming and electronics. I've only one homemade electronics design/build project under my belt- I'm very well versed in electrical and mechanical, but woefully inept at circuit design and programming.. But I'm a quick learner, so wish me luck.
I've read through you guys' forum and, noticing there are some great minds here, feel optimistic about my project.
So for the question:
I am trying to build a vacuum control unit that has one vacuum source and four valves. The problem is that instead of 4 individual actuator outputs (to relays, solenoids, etc), I need to control them using multiple combinations of 3 inputs (like some sort of 3-to-8 --> 16-to-4 setup...). (I will be also be controlling 4 more relays (conventionally), 1 servo, and 1 DC motor (with PWM)).
I am mostly just trying to find out if it can be done, but any further help with the how would be greatly appreciated as well! (Below is a diagram (truth table?) of the relationship between the inputs and outputs.)

A B C 1 2 3 4
1 0 0 0 = N/C- same as (5)
2 0 0 1 = 0 0 1 1
3 0 1 0 = 1 1 0 0
4 0 1 1 = 1 0 1 0
5 1 0 0 = 0 0 0 0
6 1 0 1 = 0 0 0 1
7 1 1 0 = 1 0 0 0
8 1 1 1 = 1 0 0 1
THANKS!!
