A driver circuit for driving a load ( 3 ) connected between an output (FO) of a first channel driver (D 1 ) and an output (RO) of a second channel driver (D 2 ). The first and second channel drivers (D 1 , D 2 ) each include switch transistors for charging and discharging the gates of upper and lower output transistors in response to a command from an input pulse, a charging/discharging circuit (A 2 , B 2 ) for determining a charging/discharging speed, and a detector circuit (A 1 , B 1 ) for detecting a state of the channel driver on the opposite side. A dead time period and a speed of charging/discharging the gates of the upper and lower output transistors are changed according to the state of the channel driver on the opposite side. Thus, it is possible to achieve a channel driver circuit which can prevent a shoot-through current, adjust an output slew rate, and obtain preferred linearity as an input-output characteristic.
