ABSTRACT:
A three-state complementary field effect integrated circuit comprises an output pre-stage circuit (11) connected to an input terminal (1) and a first and second control input (6, 5) and comprising a series connection of a first switching circuit (9), a second switching circuit (7, 8) having resistances (P5, N5) and a third switching means (10); an output circuit (12) comprising a series connection of a p type and an n type field effect transistors (P1, N1) with capacitors (C1, C2) connected between respective gates and the ground (GND). When the voltages of H and L level are applied to the first and second control input (6, 5), the resistance (P5, N5) comprised in the second switching means and the capacitors (C1, C2) connected to the gates of the transistors constitute integrating circuits. When the output voltage changes, the transistors (P1, N1) are prevented from simultaneously turning on, whereby a through current flowing into the output circuit is prevented.
