As with all Maxim devices, ESD-protection structures
are incorporated on all pins to protect against electro-
static discharges encountered during handling and
assembly. The driver outputs and receiver inputs have
extra protection against static electricity. Maxim’s engi-
neers have developed state-of-the-art structures to pro-
tect these pins against ESD of ±15kV without damage.
The ESD structures withstand high ESD in all states.
After an ESD event, the MAX3535E/MXL1535E keep
working without latchup. ESD protection can be tested
in various ways. The transmitter outputs and receiver
inputs of this product family are characterized for pro-
tection to ±15kV using the Human Body Model.
The ±15kV ESD test specifications apply only to the A,
B, Y, and Z I/O pins. The test surge is referenced to
GND2. All remaining pins are ±2kV ESD protected.
Figure 14 shows the Human Body Model, and Figure
15 shows the current waveform it generates when dis-
+3V to +5V, 2500V

100pF capacitor charged to the ESD voltage of interest,
which is then discharged into the test device through a
1.5kΩ resistor.
