Active Low Inputs 2 to 1 MUX

EveryCircuit doesn't have multiplexers so I made one... sorta. 3 nots instead of ANDs.... cheap to make. 2 Diodes... outputs Gate delay is about 20 us for I0 to return to less than 1 V. F(ABC) Left switches are the inputs B (I0) and C (I1) A is the select (Selects which one!) Bottom switch is the select for which input to activate. Active Low 2-to-1 MUX. inputs by Num. o' Variales - 1 = Selects 2^(nuimber of selects) = Inputs Selects are like on-off switches. Truth table for the selects act to tell which input is ON. Top input (I0), is ON when selects are Zero, or not, or binary zero (same thing). Input 2 (I1), is on when select is one..... 2 to 1 has 1 inputs 4 to one has 2 inputs 8 to one has 3 inputs. 16 to one has 4 inputs.
