    ESD protection can be tested in various ways; the trans-
    mitter outputs and receiver inputs of this product family
    are characterized for protection to the following limits:
    1) ±15kV using the Human Body Model
    2) ±8kV using the Contact Discharge Method specified
    in IEC1000-4-2
    3) ±15kV using IEC1000-4-2’s Air-Gap Method

    Figure 6a shows the Human Body Model, and Figure
    6b shows the current waveform it generates when dis-
    charged into a low impedance. This model consists of a
    100pF capacitor charged to the ESD voltage of interest,
    which is then discharged into the test device through a
    1.5k
    resistor.
    IEC1000-4-2
    The IEC1000-4-2 standard covers ESD testing and per-
    formance of finished equipment; it does not specifically
    refer to integrated circuits. The MAX3221E/ MAX3223E/

    INVALID IS AN INTERNALLY GENERATED SIGNAL
    THAT IS USED BY THE AUTOSHUTDOWN LOGIC
    AND APPEARS AS AN OUTPUT OF THE DEVICE.
    POWER DOWN IS ONLY AN INTERNAL SIGNAL.
    IT CONTROLS THE OPERATIONAL STATUS OF
    THE TRANSMITTERS AND THE POWER SUPPLIES.
