The voltlage circuit receives a high voltage (V1) and low voltage (V2), and outputs a reference voltage (V3) to two transistors (TP,TN) of PMOS and NMOS type respectively. The reference voltage allows the high voltage level to be transmitted through the transistor network (1). When a low voltage input level is set, the PMOS transition becomes non conducting, and produces a low voltage output in response to an input signal level (in).
