Abstract: A driver circuit for an electronic switch is described herein. According to one embodiment the driver circuit includes an input buffer with an input node for receiving a buffer input signal, a pull-down circuit coupled to the input node and a ground node, and a pull-up circuit coupled to the input node and a supply node. The driver circuit further includes control circuitry configured to activate either the pull-down circuit or the pull-up circuit. The pull-up circuit is activated when the voltage level of the buffer input signal is above a first threshold, and the pull-down circuit is activated when the voltage level of the buffer input signal is below a second threshold.
