- the gate of the transistor 153 is connected to the output of the AND gate 153 receiving the supply of the clock signal CLK at the other input terminal, while the source of the transistor 153 is grounded. Therefore, when the output signal T of the counter 150 becomes the H level, the clock signal CLK becomes the output signal S 1 of the AND gate 152 as it is, and the drain-source of the transistor 153 depends on the level. It is configured to switch between them.
