title: What is the maximum number of inputs for any logic gate?
body: <p>In the references that we use, I usually see either a 2 or 3-input logic gate. Four-input gates come by once in a while. However, is there a certain limit to the number of inputs a logic gate can have theoretically? I'm assuming in actual practice there is some sort of limit due to the increased complexity as number of input increases. But just hypothetically, are we limited to 4 (because that's the maximum I ever saw in a text by far)? Thanks.</p>
