Abstract
An integrated circuit (IC) configured for being connected to an external reference voltage uses an IC reference voltage to determine the logic levels of signals applied to the IC. The IC includes an internal reference voltage generator and logic for selecting one of the internal reference voltage and the external reference voltage for use as the IC reference voltage dependent at least in part upon the operational mode of the IC.
