_______________General Description

The MAX1406 is an RS-232 IC designed to meet the

stringent electrostatic discharge (ESD) requirements of

the European community. All transmitter outputs and

receiver inputs are protected to ±15kV using IEC1000-4-2

Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact

Discharge, and ±15kV using the Human Body Model.

The MAX1406 has three RS-232 transmitters and three

RS-232 receivers, and is optimized for operation in

printer, modem, and telecom applications. It is guaran-

teed to run at data rates up to 230kbps, providing com-

patibility with popular software for communicating with

personal computers. Power-supply current is less than

The MAX1406 is pin and functionally compatible with the

industry-standard MC145406, so existing designs can

instantly become Electromagnetic Compatibility (EMC)

compliant. The MAX1406 is available in DIP and SO pack-

ages, and in a tiny SSOP that reduces board space.
