ABSTRACT:
A variable low voltage signal translator uses a driver for outputting a low voltage signal translation. A control circuit is coupled to the driver for enabling and disabling the driver wherein the control circuit has an input coupled to the signal to be translated. One terminal of the pull-up resistor is coupled to an output of the driver. A second terminal of the pull-up resistor is coupled to a voltage supply which provides the low voltage level of the variable low voltage signal translator.
