ABSTRACT:
A voltage level translator circuit is provided that translates an input voltage referenced to an ECL supply voltage V.sub.CC to a voltage referenced to a TTL supply voltage V.sub.EE independent of power supply voltage variations. A first and a second embodiment have reference circuits coupled to receive a data input signal for providing a single signal referenced to a first supply voltage terminal to a current mirror. An output circuit is coupled to the current mirror for providing an output signal referenced to the second supply voltage terminal. A third embodiment has a reference circuit coupled to receive a data input signal for referencing a voltage on a first supply voltage terminal to a voltage on a second supply voltage terminal. A voltage setting circuit is coupled to the reference circuit for setting a voltage within the reference circuit. An output circuit is coupled to the voltage setting circuit for providing an output voltage referenced to a voltage on the second voltage terminal and independent of variations in supply voltages.
