19-1120; Rev 0; 9/96
±15kV ESD-Protected, EMC-Compliant,
230kbps, 3-Tx/3-Rx RS-232 IC
_______________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.
