ABSTRACT:
A data output circuit includes a periphery circuit connected between a supply voltage and a first ground voltage line and an output driver connected between a supply voltage and a second ground voltage line. The periphery circuit receives a first input signal and generates a first output signal on a node responsive to the first input signal, and the output driver receives a second input signal and the first output signal and generates a second output signal on an output pin in response thereto. A discharge circuit is coupled with the first ground voltage line wherein the discharge circuit allows current to flow from the first ground voltage line and wherein the discharge circuit blocks current flow to the first ground voltage line. Related methods are also discussed.
