The method of the present invention for switching an output driver 100 of the type comprising an n-mos 102 transistor and a p-mos 101 transistor configured in a push-pull arrangement operates by directly monitoring the level of the output signal OUT. The method comprises slowly switching off the input to the initially designated active transistor; monitoring the variation in output voltage level in response thereto; and when a desired change in output level is detected the switching the initially designated output transistor on completely and fast. Using this method the parasitic currents in the diodes are much smaller in time and amplitude. |
