Abstract

A transmitter circuit includes a first driver circuit configured to drive an input/output pad in an integrated circuit device, the first driver circuit including a thin-oxide transistor configured to couple the input/output pad to a first voltage rail when the transmitter circuit is operated in a first mode; a gate pullup transistor configured to couple a gate of the thin-oxide transistor to a second voltage rail when voltage of a third voltage rail is collapsed to a zero-volt level; and a switch configured to block transmission of a gating signal to the gate of the thin-oxide transistor when the voltage of the third voltage rail is collapsed to the zero-volt level.
