 | | By the "electrical state" of a logic element we mean herein the totality of eletrical signals applied to the input terminals. |
 | | The combination 100 is an embodiment of the inventive logic element, with numerals 101, 102, and 103 referring, respectively to emitter, barrier, and collector of the RST device, numerals 1040, 1041 and 1042 referring to the input terminals, and numerals 105, 106 and 107 referring to the output terminals, load resistor, and voltage source, respectively. |
 | | All logic elements according to the invention have the property that their output is logic 1 only if all inputs are at the same logic state (1 or 0), and is zero whenever all inputs are not at the same logic state. |
