<p>An interface scanning circuit consisting of arranging a current source at the input of a multiplexer (10), said current source being composed of a transistor (4) and two resistors (3), (5), the latter (5) being related and acting as an element which limits the value of the reverse current, there being also arranged an attenuating network including two resistors (7), (8), as well as a fixed-pass filter-condenser related to said attenuating network.. <IMAGE></p> |
