OK for now since im just trying to learn about these switches lets keep it to just digital.
I have 4 digital outputs based on 8 inputs
I would like a switch which will let me switch between 2 settings:
Use Digital Input 1-4
OR Digital Input 5-8
The digital signals are TTL (5V DC, <10mA and dont care about switching speed)
My supply is 5V.
Signals only go one way
Lower closed resistance is better as I would like to avoid a huge voltage drop that would make my TTL signals stop working
Open resistance... if one input was high and one input was low I would still want the TTL to work.
