Abstract
A threshold-effect integrated logic circuit of the I.sup.2 L type with hysteresis including a trigger circuit and an amplifier. The difference between the two voltage thresholds of the trigger circuit is controlled by an interrupting unit, and is equal to the voltage drop across a diode. The difference between each threshold and the output level results in an immunity to long-term spurious signals and static noise.
