MAX1406EWE+T

P1-P3P4-P6P7-P8
_______________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
500µA for I
DD
and I
SS,
and less than 1mA for I
CC.
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
