ABSTRACT:
An interface circuit adapted to receive an analog input signal for generating first and second output signals at respective outputs in response to the input signal varying above a first reference voltage level and varying below a second reference voltage level. The interface circuit comprising first and second circuits each of which has an input coupled to the input of the interface circuit and receiving the first and second reference voltage levels respectively. Each one of the two circuits includes a voltage translation circuit for translating the reference voltage level supplied thereto and a comparator to produce the particular output signal in response to the input signal level assuming the aforementioned relationship with respect to the respective two reference voltage levels.
