Abstract
A voltage level-shifting circuit for an integrated circuit includes an input terminal receiving a voltage signal referenced to an input/output (I/O) voltage level. A transistor overvoltage protection circuit includes a first p-type metal oxide semiconductor (PMOS) transistor includes a source coupled to the second voltage supply, a gate receiving an enable signal, and a drain connected to a central node. A first n-type metal oxide semiconductor (NMOS) transistor includes a drain connected to the central node, a gate connected to the input terminal, and a source connected to an output terminal. A second NMOS transistor includes a drain connected to the input terminal, a gate connected to the central node, and a source connected to the output terminal.
