Maxim is the only RS-232 IC manufacturer to specify and achieve ±15kV ESD protection using both the
human body model and the IEC 801-2 air-gap discharge method (see sidebar). Maxim's extended ESD
protection eliminates the need for costly external protection devices such as TransZorb™, while preventing
expensive field failures.
To further simplify RS-232 applications, Maxim has recently introduced transceivers that shut down
automatically when not in use, reducing supply current to 1µA—a thousand-fold improvement over other
parts. This action helps extend battery life in portable equipment such as notebook computers, palmtop
computers, and bar-code scanners.
Also simplifying applications is an internal, digitally controlled switch that transforms a Maxim RS-232
transceiver from a DTE port (Data Terminal Equipment) to a DCE port (Data Communications Equipment).
The Move to 3V Operation
The standard supply voltage for notebook computers and other portable equipment is rapidly changing to
3V. To meet the needs of this market, many 5V RS-232 devices have been recharacterized for 3V
operation. While these parts do not generate the ±5V output swings required by RS-232 communications,
they do meet the EIA/TIA-562 requirements of ±3.7V output swings. EIA/TIA-562 is interoperable with RS-
232, although its output voltage is not sufficient to power a mouse, whose microcontroller typically requires
5mA at 5V.
To overcome the limitations of these recharacterized devices, Maxim has developed the MAX3241 family of
