Abstract
An interface circuit includes at least one semiconductor logic gate and a latch circuit. The semiconductor logic gate configured to receive an input signal having a signal level changeable and outputs a logic gate signal which has a signal level becoming a low level when a signal level of the input signal is not less than a logic threshold value, alternatively has a signal level becoming a high level when a signal level of the input signal is less than the logic threshold value. The latch circuit fetches the logic gate signal as a first latch signal, while fetching a signal which is converted from the input signal and has a signal level varying between a second voltage and the ground potential, alternatively, the input signal as a second latch signal, to output the first interface output signal and the second interface output signal.
