If your 3.3V device inputs are not 5V tolerant and your 5V inputs lack 3.3V compatible thresholds then sadly you won’t be able to interface them across voltage levels without a shifter circuit.

Domain wall gate for magnetic logic and memory applications with perpendicular anisotropy. Nanotechnology, 2014 DOI: 10.1109/IEDM.2013.6724684 ...

Contemporary logic circuits use MOSFETs as the elements to build gates, but there are many ways to implement them. Using relays is one of them, and you can literally see how they work.

High-frequency firing activity can be induced either naturally in a healthy brain as a result of the processing of sensory stimuli or as an uncontrolled synchronous activity characterizing epileptic ...

Non-volatile bistable memory circuits being developed by Satoshi Sugahara and his team at Tokyo Tech pave the way for highly energy-efficient CMOS logic systems. The details are described in the ...
