PROBLEM TO BE SOLVED: To provide a voltage level translator circuit for interfacing between multiple voltage levels that does not suffer from problems exhibited by conventional voltage level translator circuits. SOLUTION: The voltage level translator circuit is selectively operable in one of at least two modes in response to a control signal. In a first mode, the voltage level translator circuit is operative to translate an input signal referenced to a first power supply providing a first voltage to an output signal referenced to a second power supply providing a second voltage. In a second mode, the voltage level translator circuit is operative to provide a signal path from an input of the voltage translator circuit to an output thereof without translating the input signal. The control signal is indicative of a difference between the first voltage and the second voltage. COPYRIGHT: (C)2006,JPO&NCIPI |
