Abstract
A latch circuit receives complementary signals and consists of an nMOS transistor whose source is connected to an input terminal of the latch circuit and a series-connected circuit consisting of first and second pMOS transistors arranged between and connected to a drain terminal of the nMOS transistor and a high-potential power supply. The complementary signals are a first signal and a second signal that is an inversion of the first signal. Each of the signals has a pulse characteristic that rising time is longer than falling time. The latch circuit latches a quick fall by passing the first signal through the nMOS transistor. On the other hand, the latch circuit latches a slow rise by turning on the second pMOS transistor in response to a fall in the second signal.
