An on-chip driver is described for applications voltage output signals are desired from a digital sub-micron CMOS integrated circuit. The driver includes a signal buffer, signal level shifter, output pull-up, and an output pull-down. The signal buffer is coupled to a digital CMOS input for generating a corresponding buffered signal that is received by both the output-up down and the level shifter. The output pull-down is responsive to the buffered signal and operates to pull the output of the driver to a low voltage level of about 0 volts when the digital CMOS input is at a low logic state. Further, the level shifter is responsive to the buffered signal for generating a voltage shifted signal that is received by the pull-up which pulls the output of the driver to a high voltage level of 2.5 volts or greater when the digital CMOS input is at a high logic state. |
