As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against electrostatic
discharges encountered during handling and assembly.

electricity. Maxim’s engineers have developed state-of-
the-art structures to protect these pins against ESD of
±15kV without damage. The ESD structures withstand
high ESD in all states: normal operation, three-state
output mode, and powered down. After an ESD event,
Maxim’s E versions keep working without latchup,
whereas competing products can latch and must be
powered down to remove latchup.
ESD protection can be tested in various ways. The I/O

protection to the following limits:
1) ±15kV using the Human Body Model
2) ±8kV using the Contact Discharge method specified
3) ±10kV using IEC 1000-4-2’s Air-Gap Discharge
ESD performance depends on a variety of conditions.

test setup, test methodology, and test results.
Figure 3a shows the Human Body Model and Figure 3b
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 inter-
est, which is then discharged into the test device
through a 1.5kΩ resistor.

The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment; it does not specifi-
cally refer to integrated circuits. The MAX3372E–
MAX3379E and MAX3390E–MAX3393E help to design
equipment that meets Level 3 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. Hence, the ESD with-
stand voltage measured to IEC 1000-4-2 is generally
lower than that measured using the Human Body Model.
Figure 4a shows the IEC 1000-4-2 model, and Figure 4b
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 con-
nects the probe to the device before the probe
is energized.
The Machine Model for ESD tests all pins using a
200pF storage capacitor and zero discharge resis-
tance. Its objective is to emulate the stress caused by
contact that occurs with handling and assembly during
manufacturing. Of course, all pins require this protec-
tion during manufacturing, not just inputs and outputs.
Therefore, after PCB assembly, the Machine Model is
less relevant to I/O ports.
