MAX13000E–MAX13005E
Ultra-Low-Voltage Level Translators

structures withstand high ESD in all states: normal
operation, tri-state output mode, and power-down. After
an ESD event, Maxim’s E-versions keep working with-
out latchup, whereas competing products can latch
and must be powered-down to remove latchup.
ESD protection can be tested in various ways. The
I/OV
CC
lines of the MAX13000E–MAX13005E are char-
acterized for protection to ±15kV using the Human
Body Model.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.
Human Body Model
Figure 10 shows the Human Body Model and Figure 11
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.
