to ±15kV without damage or latch-up. The MAX3188E/
MAX3189E’s transmitter output is characterized for pro-
tection to the following limits:
±15kV using the Human Body Model
±8kV using the Contact Discharge method specified
in IEC 1000-4-2
±15kV using the Air-Gap Discharge method specified
in IEC 1000-4-2
Human Body Model
Figure 2 shows the Human Body Model, and Figure 3
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,
and then discharged into the test device through a
1.5k
resistor.
IEC 1000-4-2
The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment; it does not specifi-
cally refer to ICs. The MAX3188E/MAX3189E 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 4 shows the IEC 1000-4-2
model, and Figure 5 shows the current waveform for
the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge
test. The Air-Gap test involves approaching the device
with a charged probe. The Contact Discharge method
connects the probe to the device before the probe is
energized.
Power-Supply Decoupling
In most circumstances, 0.1F bypass capacitors are
adequate for power-supply decoupling. Connect the
bypass capacitors as close to the IC as possible.
