<p>A low quiescent power circuit for driving an output between two voltage states in response to a control signal is disclosed. The circuit comprises a first switch (15) including first (16) and second (18) terminals that provides a conductive path from a first source of potential (19) to an output terminal (22) when the potential difference between the control terminals is less than a threshold value and for electrically isolating the first source of potential (19) from the output terminal (22) when the potential difference between the control terminals is greater than the threshold value, and a second switch (20) that provides a conductive path between a second source of potential (21) and the output terminal (23) when the first switch (15) electrically isolates the first source of potential (19). The second switch (20) electrically isolates the output terminal from the second source of potential (21) when the first switch (15) is conductive. The circuit also includes a circuit for controlling the first and second switches in response to a logic level control signal.</p> |
