In a circuit to convert a first logic signal having a first range to a second logic signal having a second range, a first metal oxide semiconductor (MOS) transistor selectively couples an output node to a first reference voltage when the output node is to be in a first state. A source-follower circuit includes a current source and a source follower output, and the source follower output is coupled to the output node. A second MOS transistor selectively couples the source-follower circuit to a second reference voltage when the output node is to be in the second state.
