Abstract
A multi-voltage, high voltage I/O buffer in low-voltage technology is disclosed. In one embodiment, the I/O buffer includes a logic circuit configured to generate a signal based on a data signal and a first control signal. A level shifter is coupled between a supply voltage terminal and a ground terminal, and the level shifter is generates first and second output signals in first and second voltage domains, respectively, at first and second nodes, respectively, based on the signal from the logic circuit. A control circuit is coupled between the second node and a third node. The control circuit transmits the second output signal to the third node when the first control signal is asserted, and the control circuit couples the third node to the ground terminal when the first control signal is not asserted.
