Abstract:
A push-pull switch comprising:a first N-channel MOS transistor (M1), wherein a drain-source path of which is connected between a voltage terminal (10) and an output terminal (13); a first resistor (20) connected between the gate of the first N-channel MOS transistor and the high voltage terminal; a diode (D) having its anode connected to the output terminal (13) and its cathode connected to the gate of the first N-channel MCS transistor; a second N-channel MOS transistor (M2) having its drain connected to the cathode of the diode, its source connected to a reference potential, and its gate connected to a control terminal; and a second resistor (40) connected between the gate of the second N-channel MOS transistor and the output terminal (13).
