PROBLEM TO BE SOLVED: To reduce noise by reducing an operating time difference between a pair of MOSFETs of an output stage.SOLUTION: A PMOSFET 1 and an NMOSFET 2 are connected between a DC power supply VD and an output terminal CANH and between an output terminal CANL and a ground, respectively. The PMOSFET 1 is driven from an input terminal S via a first pre-buffer circuit 5, and the NMOSFET 2 is driven from the input terminal S via an inverter circuit 7 and a second pre-buffer circuit 6. The output terminal CANH is connected to a gate of the NMOSFET 2 via a capacitor 3, and the output terminal CANL is connected to a gate of the PMOSFET 1 via a capacitor 4. If the PMOSFET 1 operates first, the capacitor 3 can rapidly drivingly increase a gate potential of the NMOSFET 2. If the NMOSFET 2 operates first, the capacitor 4 functions similarly. |
