ABSTRACT:
A latch circuit includes a current source, and a flip-flop amplifier circuit having a pair of first and second input terminals for comparing a reference voltage and an external input voltage with each other and amplifying the voltage difference therebetween in response to inputting of an activating signal. A first transistor has a source terminal, a drain terminal connected to the first input terminal of the flip-flop amplification circuit, and a gate terminal receptive of the external input voltage. A second transistor has a source terminal connected to the source terminal of the first transistor, a drain terminal connected to the second input terminal of the flip-flop amplification circuit, and a gate terminal receptive of the reference voltage. A pair of gate elements are connected in series between the sources of the first and second transistors and the current source, and operate after the completion of amplification of the voltage difference in the flip-flop amplifier circuit for cutting off a drain current flowing through the first and second transistors so as to enable the flip-flop amplifier circuit to latch the external input voltage.
