RS-232 is a standard for serial communication that has long been used for electrical connections of terminal equipment. Even though a legacy bus, RS-232 is still widely prevalent today in serial communication. From telecommunications equipment to industrial machinery and test and measurement equipment. RS-232 is vulnerable to ESD and transient voltage threats. Semtech has a strong portfolio of ESD protection devices idea for safeguarding RS-232 ports from the most harsh electrical transient threats.
