MAX3187:±15kV ESD-Protected, EMC-Compliant, 230kbps, Dual RS-232 Serial Port for Motherboards/Desktops

The MAX3187 complete, dual DTE RS-232 serial port meets 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 MAX3187's six RS-232 transmitters and ten RS-232 receivers require no charge pump. Guaranteed to run at data rates up to 230kbps, the MAX3187 is optimized for desktop PC and motherboard applications, and is compatible with popular software for PC communications. Power-supply current is less than 1mA for IDD and ISS, and less than 3mA for ICC. The MAX3187 is available in a space-saving 36-pin SSOP package.
