摘要
A five volt tolerant integrated circuit signal pad having an initial fast pull-up to three volts and then operating as an open drain output with an external resistor for pulling up the output from about three volts to about five volts. The initial fast (active) pull-up is accomplished with active devices that reduces the overall pull-up time of a newer technology (lower operating voltage) integrated circuit output when transitioning from a logic 0 to a logic 1. Circuits of the integrated circuit output driver protect the internal operating circuit nodes from excessive voltage and leakage currents that would otherwise result from a voltage on the signal pad that is more positive than the operating voltage of the integrated circuit.
