LC2574N
Typical Application
Electronic equipment is susceptible to damage caused by a variety of sources, including Electrostatic Discharge
(ESD), Electrical Fast Transients (EFT) and Lightning strikes. The LC2574N is designed to protect the sensitive
equipment from damage which may be induced by such transient events. This product can be configured in different
connections to meet the requirement of common-mode and differential-mode as follows:
