Abstract

PURPOSE:To keep noise margin required for variance of external conditions easily, by giving a hysteresis to the input and output characteristics of gates according to the conditions, in an integrated logical circuit. CONSTITUTION:A reference voltage VRA1 of a current switching type logical gate G1 takes binary value to the logical operation of an input signal. Outputs 01, 02 of the gate G1 are connected to gates G2, G3, and output lines l1, l2 different in the phase are connected to the point (a), and when an input VIN1 is at low level, the output line l1 turns on, and the potential at the point (a) is Rri I2, and when the input VIN1 is at high level, the output line l2 turns on and the potential at the point (a) is Rri I3. If I2 I3, the VRA1 takes binary value depending on the level of the VIN1, the input and output characteristics of the G1 have a hysteresis, and when I2<I3, the noise margin of each logical level can be increased.
