Output driver for mixed supply voltage system

摘要

An output driver for mixed voltage systems includes an input line for receiving a signal to be output. The circuit also includes an overvoltage generator, coupled between the input line and an output stage. The overvoltage generator boosts a level of the signal to a second voltage before it reaches the output stage. A restore circuit is also provided which restores the second voltage with every transition of the input signal. <IMAGE>
