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 communica-
tions. Power-supply current is less than 1mA for I
and I
The MAX3187 is available in a space-saving 36-pin
SSOP package.
