Abstract
A logic element, particularly a bipolar gate circuit for an LSI-circuit, employing a pair of Schottky-diodes, a pair of resistances and a transistor, with the diodes, connected in high resistance direction, to respective inputs, the other sides of the diodes being connected in common to a first resistance and to the base of the transistor, with said first resistance being operatively connected to a reference potential, said second resistance connecting the collector of the transistor, and the common connection of said diodes.
Claims1
A logic element, particularly a bipolar gate circuit for an LSI-circuit, comprising a pair of Schottky-diodes, a pair of resistances and a transistor, a first input to which a terminal of a first of said diodes is connected in high resistance direction, a second input to which a terminal of the second of said diodes is connected in high-resistance direction, the second terminals of said diodes being connected to one terminal of a first resistance and to the base of said transistor, the other terminal of said first resistance being connected to a reference potential, said second resistance having one terminal connected to the collector of said transistor, and the other terminal thereof, being connected to the second terminal of said diodes, and a second transistor having its emitter-collector path operatively disposed between the second terminal of said diodes and the associated terminal of the first resistance.
