ABSTRACT:
A programmable logic device having a plurality of gates which can be programmed to implement a plurality of product terms for representing logic functions, wherein an input signal is processed according to the logic functions, and a resulting output signal is generated having a selectable output voltage level. A desired output voltage level is specified. A generator supplies the desired output voltage to an output buffer of the programmable logic device. This generator may operate independently from the generator used to supply power to the programmable logic device. The processed signal drives the output buffer, and the output signal from the output buffer corresponds to the desired output voltage.
