The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment; it does not specifi-
cally refer to ICs. The MAX3180E–MAX3183E enable the
design of equipment that meets the highest level (Level
4) of IEC 1000-4-2 without the need for additional ESD-
protection components.
The major difference between tests done using the
Human Body Model and IEC 1000-4-2 is higher peak
current in IEC 1000-4-2. Because series resistance is
lower in the IEC 1000-4-2 model, the ESD withstand
voltage measured to this standard is generally lower
than that measured using the Human Body. Figure 5
shows the IEC 1000-4-2 model, and Figure 6 shows the
±15kV ESD-Protected, 0.5µA, +3V to +5.5V,
1.5Mbps RS-232 Receivers in SOT23-5

ESD Contact Discharge test.
The Air-Gap test involves approaching the device with
a charged probe. The Contact Discharge method con-
nects the probe to the device before the probe is ener-
gized.
In most circumstances, a 0.1µF V
is adequate. Connect the bypass capacitor as close to
the IC as possible.
