ABSTRACT:
A flip-flop circuit of set-reset type comprising complementary MOS transistors.
The flip-flop circuit comprises a first CMOS NOR circuit to which set signal is applied, and a second CMOS NOR circuit having same arrangement as the first CMOS NOR circuit and to which reset signal is applied.
Set signal is the logical product signal of first set signal and second set signal. Reset signal is the logical product signal of first reset signal and second reset signal. Neither of first set and reset signals becomes logic "1" simultaneously. Second set and reset signals are kept either unchanged during the time period when first set and reset signals are logic "1" or become logic "1" only during the time period when first set and reset signals are logic "1".
The first NOR circuit comprises first and second transistors of first conductivity type connected in series between first power supply terminal and third transistor, third and fourth transistors of second conductivity type, and a fifth transistor of second conductivity type connected between the node of second and third transistors and the second power supply terminal. First set signal is applied to gates of first and fourth transistors and second set signal to the gate of third transistor. The second transistor is gate-connected to the fifth transistor.
