ESD PROTECTIO
U
ESD Test Circuit
The RS232 line inputs of the LT1331 have on-chip protec-
tion from ESD transients up to
±10kV. The protection
structures act to divert the static discharge safely to
system ground. In order for the ESD protection to function
effectively, the power supply and ground pins of the
LT1331 must be connected to ground through low imped-
ances. The power supply decoupling capacitors and charge
pump storage capacitors provide this low impedance in
normal application of the circuit. The only constraint is that
low ESR capacitors must be used for bypassing and
charge storage. ESD testing must be done with pins VCC,
VL, V
+, V– and GND shorted to ground or connected with
low ESR capacitors.
