MAX3185:±15kV ESD保护、符合EMC标准、230kbps RS-232串口,适用于主板/台式PC

The MAX3185 is a complete DTE RS-232 serial port designed to meet the stringent ESD requirements of the European community. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. The MAX3185 has three RS-232 transmitters, five RS-232 receivers, and no charge pump, optimizing it for operation in desktop PC and motherboard applications. It is guaranteed to run at data rates up to 230kbps, providing compatibility with popular software for communicating with personal computers. Power-supply current is less than 300µA for IDD and ISS, and less than 1mA for ICC. The MAX3185 is pin and functionally compatible with the industry-standard 75185, so existing designs can instantly become EMC compliant. The MAX3185 is available in an SO package and in the tiny SSOP that further reduces board space.
