An electrostatic protection circuit includes first and second diodes, a resistor and a capacitor, an inverter configured to invert a signal to output an inverted signal to a gate-coupled transistor, a first switch configured to block a first leakage current from flowing through a pull-up driver in response to the inverted signal, and a second switch configured to block a second leakage current from flowing through a pull-down driver in response to the signal.
