ABSTRACT:
A latch circuit includes first, second, and third inverter circuits, a switching element, and a capacitor element. The first inverter circuit and the second inverter circuit are cross-connected to each other. The third inverter circuit logically inverts an output from the first inverter circuit. The switching element is connected between the output terminal of the second inverter circuit and the output terminal of the third inverter circuit. The capacitor element is connected between the output terminal of the third inverter circuit and a reference voltage node.
