ABSTRACT:
An input buffer to which an ECL logic swing is applied through a voltage level shifter to one input of a differential pair of switching devices, the other input of the differential pair being a voltage level shifted by the same amount from an ECL logic reference voltage. The output across a load device coupling one of the switching devices to a collector voltage source drives the input of a conventional inverter coupling a reduced MOS logic voltage supply to the collector voltage source. An output buffer to which a reduced MOS voltage swing logic input is applied to the input of a conventional inverter coupling a reduced MOS logic voltage supply to a collector voltage source. The output of the inverter is applied to one input of a differential pair of switching devices having the other input thereto held at a reference level defined by a voltage divider. The output of the differential pair across a load device coupling one of the switching devices to the collector voltage source is level shifted through another switching device to the circuit output.
