Abstract
A latch circuit switches a differential operation performed by a differential operation circuit including a first logic circuit, a second logic circuit, a third logic circuit, and a fourth logic circuit and a single end operation performed by a single end operation circuit according to a logic level of an inputted selection signal. The latch circuit performs an operation to output an input signal and an inverted input signal without change from a first output terminal and a second output terminal of the latch circuit, respectively, and an operation to set the input signal and the inverted input signal in a hold state in the differential operation and performs an operation to output the input signal from the first output terminal without change and an operation to set the input signal in a hold state in the single end operation, according to a clock signal and an inverted clock signal.
