High threshold logic circuits are used in place of a diode driven logic where voltage noise may cause it to produce an unwanted output. Below 1 volt is a logical zero and above 3 volts is a logical one. For more info, you might want to do a search for "Zenier Diode." They are often used in high threshold logic circuits.
