An output buffer provides high current at an output for only a brief period, while after this brief period the output buffer only supplies a limited amount of current to the subsequent stage. One embodiment of this inventive output buffer utilizes the inherent delay of an inverter and a high current FET device, arranged to form a feedback circuit, to switch off high current supplied to the subsequent stage afer a brief period. This brief period allows the output of the output buffer to supply the necessary current and voltage to switch the subsequent stage. A low current FET device in the output buffer then provides the necessary low current to maintain the state of the subsequent stage without supplying current unnecessary for the proper operation of the subsequent stage.
