General Description
The MAX3222E/MAX3232E/MAX3237E/MAX3241E/
MAX3246E +3.0V-powered EIA/TIA-232 and V.28/V.24
communications interface devices feature low power
consumption, high data-rate capabilities, and enhanced
electrostatic-discharge (ESD) protection. The enhanced
ESD structure protects all transmitter outputs and receiver
inputs to ±15kV using IEC 1000-4-2 Air-Gap Discharge,
±8kV using IEC 1000-4-2 Contact Discharge (±9kV for
MAX3246E), and ±15kV using the Human Body Model.
The logic and receiver I/O pins of the MAX3237E are pro
-
tected to the above standards, while the transmitter output
pins are protected to ±15kV using the Human Body Model.
A proprietary low-dropout transmitter output stage deliv-
ers true RS-232 performance from a +3.0V to +5.5V
power supply, using an internal dual charge pump. The
charge pump requires only four small 0.1μF capacitors
for operation from a +3.3V supply. Each device guaran-
tees operation at data rates of 250kbps while maintaining
RS-232 output levels. The MAX3237E guarantees opera-
tion at 250kbps in the normal operating mode and 1Mbps
in the MegaBaud™ operating mode, while maintaining
RS-232-compliant output levels.
The MAX3222E/MAX3232E have two receivers and two
transmitters. The MAX3222E features a 1μA shutdown
mode that reduces power consumption in battery-pow-
ered portable systems. The MAX3222E receivers remain
active in shutdown mode, allowing monitoring of external
devices while consuming only 1μA of supply current. The
MAX3222E and MAX3232E are pin, package, and func-
tionally compatible with the industry-standard MAX242
and MAX232, respectively.
The MAX3241E/MAX3246E are complete serial ports
(three drivers/five receivers) designed for notebook and
subnotebook computers. The MAX3237E (five drivers/
three receivers) is ideal for peripheral applications that
require fast data transfer. These devices feature a shut-
down mode in which all receivers remain active, while
consuming only 1μA (MAX3241E/MAX3246E) or 10nA
(MAX3237E).
The MAX3222E, MAX3232E, and MAX3241E are avail-
able in space-saving SO, SSOP, TQFN and TSSOP pack-
ages. The MAX3237E is offered in an SSOP package.
The MAX3246E is offered in the ultra-small 6 x 6 UCSP™
package.
