An input of the inverter is connected to a first node. A target inversion potential is higher than an inversion potential of the inverter. The first path control circuit electrically disconnects the first node from an input terminal if an input potential is lower than the target inversion potential, and electrically connects the first node to the input terminal if the input potential is higher than the target inversion potential. The second path control circuit electrically connects the first node to a ground terminal if the input potential is lower than a second inversion potential lower than the target inversion potential, and electrically disconnects the first node from the ground terminal if the input potential is higher than the second inversion potential.

    摘要: PROBLEM TO BE SOLVED: To provide a control signal generating circuit suitable for controlling a semiconductor device.SOLUTION: A Johnson counter 31 includes flip-flops FF1-FF4 and gate circuits 41-44. It changes control signals C1-C4 to an "H" level in response to start signals ST1-ST4 that are sequentially inputted, and then, the control signals C1-C4 are changed to an "L" level in response to stop signals SP1-SP4 that are sequentially inputted. Thus, without using many flip-flops, the control signals C1-C4 are sequentially changed to the "H" level and the "L" level with a desired time interval.
