Interference-immunized multiplexer

A method implemented in a multiplexer, the method comprising:

• receiving, by a first selection input of a first buffer, a first selection signal;
• receiving, by a second selection input of a second buffer, a second selection signal;
• receiving, by a first logical input of the first buffer, a first logical input signal;
• receiving, by a second logical input of the second buffer, a second logical input signal;
• coupling, by the multiplexer and when the first selection signal has a first value, the first logical input to a third logical input of an output circuit to produce the first logical input signal to the third logical input;
• coupling, by the multiplexer and when the first selection signal has a second value, the first logical input to a first ground of the first buffer;
• coupling, by the multiplexer and when the second selection signal has the first value, the second logical input to a fourth logical input of the output circuit to produce the second logical input signal to the fourth logical input;
• and
• coupling, by the multiplexer and when the second selection signal has the second value, the second logical input to a second ground of the second buffer.
