I am looking for a device which I do not know exists.
I would like to store the state of a number of analog switches, perhaps driven by a D Type Flip Flop.
I'd like to drive the flip flop and set values with a momentary toggle switch.
What I am looking for is a type of analog switch, which could store memory and survive power downs without relying on some sort of constant power source like a small battery. Basically a parallel accessed EEPROM with direct access to each of the bits through a single pin, or something that behaves in a similar fashion.
Can anyone think of a solution to this problem? Does something like this exist? My research came up with bistable multivibrators, but I could not find information that indicates if those would survive a power down or not. Cost and size are of concern to the design, of course.
