ESD Protection
All of the MAX7360 pins meet the 2kV Human Body Model
ESD tolerances. Key-switch inputs and GPIOs meet IEC
61000-4-2 ESD protection. The IEC test stresses consist
of 10 consecutive ESD discharges per polarity, at the
maximum specified level and below (per IEC 61000-4-2).
Test criteria include:
1) The powered device does not latch up during the
ESD discharge event.
2) The device subsequently passes the final test used
for prescreening.
Tables 5 and 6 are from the IEC 61000-4-2: Edition 1.1
1999-05: Electromagnetic compatibility (EMC) Testing
and measurement techniques—Electrostatic discharge

X = Open level. The level has to be specified in the
dedicated equipment specification. If higher voltages
than those shown are specified, special test equipment
could be needed.
