ABSTRACT:
A source-coupled FET-logic-type logic circuit having level shift elements connected to a high-potential power supply, field-effect transistors, load elements connecting the sources of the field-effect transistors, field-effect transistors coupled between the high-pontential power supply and a low-potential power supply, constant current sources, and complementary output terminals. The circuit further has a field-effect transistors controlled by complementary signals input to two input terminals. The circuit, which is a T flip-flop, further comprises a frequency switching circuit composed of field-effect transistors which are controlled by the signals supplied to two switching terminals. When the first switching terminal is at a high level, the output terminals outputs a signal having the same frequency as the input signal. When the first switching terminal is at a low level, the output terminals outputs a signal having half the frequency of the input signal.
