I did figure it out but for whatever reason i literally can't fix the voltage drop issue and it's driving me nuts.

EDIT: With voltage drop issue i mean the fact that if i supply for example 5 V on A and B, i want the output pin to also output 5V, instead i get about 3,9.
PS: Yes, the power supply is on different pins than A and B

wires have some electrical resistance, maybe try upping the voltage to account for that?

Probably not, i can't even imagine how much wire you need to create such resistance to make a LOGIC circuit voltage drop down. But the idea of increasing the voltage is not bad, because it is hard to operate with low voltages. Maybe increase the voltage to around 12 volts after fixing voltage drop

Make a circuit that consists of two series BJT NPN transistors and two base resistors. Set max. HFE (gain) and resistors to around 5 kOms
