    摘要: A logic circuit having a differential amplifier comprising a transistor pair of first (T₁) and second (T₂) transistors and further comprising a third transistor (T₃) connected in parallel with the second transistor (T₂), a first driving circuit (1) operatively connected to drive the first and second transistors with complementary output signals (A, A ) having a first (H₁) and second (L₁) levels, and a second driving circuit (2) operatively connected to drive the third transistor (T₃) with an output signal (B) having third (H₂) and fourth (L₂) levels, one (H₂) of which third and fourth levels is beyond one end of the range between the first and second levels and the other (L₂) of which levels is either within that range or beyond the other end of that range.
