Abstract
An output buffer circuit for supplying a current to an output pad of an integrated circuit comprises an output driver circuit and a feedback circuit. The output driver circuit includes a first current supply element for supplying a small current to the output pad in response to an input logic signal. The feedback circuit includes a second current supply element for supplying a large current to the output pad and a circuit for generating a feedback voltage to control the second current supply element. The feedback voltage is responsive to the input logic signal and inversely follows the output pad voltage when the output pad voltage crosses a threshold. The output buffer provides excellent short circuit protection.
