Ah, Thank you very much! I want to connect the encoder to an atmega 32U4 And the IO pins state low up to 0.9v. That’s very close to the 0.8v. Should I put two resistors in series with the signal pins to reduce the voltage a bit? I am not sure about the value though if I want to reduce by, let's say, 0.5v because there is supply current and output current. Does supply current already include output current?
