jpanhalt Well-Known Member Most Helpful Member Mar 16, 2013 #2 Is a switch or relay a diode? The buffer you mention does not conduct current from input to output. The output current is a function of the chip, not the input current drive ability. In a diode, the two are related. John

J JoeWawaw Member Mar 16, 2013 #3 yes i agree, but if i were to put a voltage in the output of the buffer, would the input go high?
