±15kV ESD Protection
ESD-protection structures are incorporated on all pins
to protect against electrostatic discharges encountered
during handling and assembly. The driver outputs and
receiver inputs of the MAX13234E–MAX13237E 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:
normal operation, shutdown, and powered down. After

an ESD event, Maxim’s E versions keep working without
latchup. ESD protection can be tested in various ways;
the transmitter outputs and receiver inputs of this prod-
uct family are characterized for protection to the follow-
ing limits:
1) ±15V Using the Human Body Model
2) ±15kV Using IEC 61000-4-2 Air-Gap Method
3) ±8kV Using IEC 61000-4-2 Contact-Discharge
