ABSTRACT:
A technique and circuitry to interface an integrated circuit to other circuits in a mixed-voltage mode environment. The integrated circuit operates at an internal supply voltage level. Externally, the integrated circuit will interface with an external supply voltage level, above the internal supply voltage level. The output signals from the integrated circuit will be compatible with the external supply level. Specifically, a level shifter (1317) or similar conversion circuit is used to convert voltages compatible with the internal supply level to be compatible with the external supply level.
