PURPOSE:To reduce the undershoot of a digital signal pulse by driving one of 1st and 2nd semiconductor switches with the output pulse of a nondelay driver circuit and driving the other with the output pulse of a delay driver circuit, and sending out a digital signal. CONSTITUTION:This circuit is equipped with the nondelay driver circuit 2 which receives a control signal pulse for controlling the digital signal and outputs a pulse rising and falling speedily when the control signal pulse rises and falls and the delay driver circuit 3 which receives the control signal pulse and outputs a pulse rising speedily when the control signal pulse rises and falls with constant delay time when the control signal pulse falls. Then one of the 1st and 2nd semiconductor switches 1a and 1b is driven with the output pulse of the nondelay driver circuit 2 and the other is driven with the output pulse of the delay driver circuit 3 to send out the digital signal. Consequently, the undershoot of the digital signal pulse sent out to the circuit is reduced. |
