Abstract:
An integrated circuit for use in an electrical system having at least one predetermined logic voltage level, the integrated circuit comprising:at least one power supply input, for receiving a power supply voltage level unequal to and independent from, the predetermined logic voltage level; at least one signal input, for receiving a logic signal having the at least one predetermined logic voltage level during at least one interval; control logic, coupled to the power supply input, for generating a digital signal; a signal output, for outputting a digital logic signal from the integrated circuit; and switching means, coupled to the control logic, the signal output, and the at least one signal input, for selectively switching the at least one signal input to the signal output, in response to the control logic, so as to generate the digital logic signal having at least one voltage level substantially equal to the at least one predetermined logic voltage level.
