Abstract
A latch circuit includes an input part receiving an external input signal; a plurality of CMOS inverter circuits divided into a first group that includes a first CMOS inverter circuit and a second CMOS inverter circuit outputting inverted data with respect to the input signal, and a second group that includes a third CMOS inverter circuit and a fourth CMOS inverter circuit outputting the same data as the input signal; and a feedback path through which the input signal is fed back to the input part via the plurality of CMOS inverter circuits, wherein a second-polarity drain belonging to one of the first CMOS inverter circuit and the second CMOS inverter circuit is arranged between a first-polarity drain belonging to the first CMOS inverter circuit and a first-polarity drain belonging to the second CMOS inverter circuit.
