The MAX3228E/MAX3229E are +2.5V to +5.5V pow-

ered EIA/TIA-232 and V.28/V.24 communications inter-

faces with low power requirements, high data-rate

capabilities, and enhanced electrostatic discharge

(ESD) protection, in a chip-scale package (UCSP™).

All transmitter outputs and receiver inputs are protect-

ed to ±15kV using IEC 1000-4-2 Air-Gap Discharge,

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

±15kV using the Human Body Model.

The MAX3228E/MAX3229E achieve a 1µA supply cur-

rent with Maxim’s AutoShutdown™ feature. They save

power without changes to existing BIOS or operating

systems by entering low-power shutdown mode when

the RS-232 cable is disconnected, or when the trans-

mitters of the connected peripherals are off.

The transceivers have a proprietary low-dropout trans-

mitter output stage, delivering RS-232 compliant perfor-

mance from a +3.1V to +5.5V supply, and RS-232

compatible performance with a supply voltage as low

as +2.5V. The dual charge pump requires only four

small 0.1µF capacitors for operation from a +3.0V sup-

ply. Each device is guaranteed to run at data rates of

250kbps while maintaining RS-232 output levels.

The MAX3228E/MAX3229E offer a separate power-sup-

ply input for the logic interface, allowing configurable

logic levels on the receiver outputs and transmitter

inputs. Operating over a +1.65V to V

vides the MAX3228E/MAX3229E compatibility with mul-

tiple logic families.

The MAX3229E contains one receiver and one transmit-

ter. The MAX3228E contains two receivers and two

transmitters. The MAX3228E/MAX3229E are available

in tiny chip-scale packaging and are specified across

the extended industrial temperature range of -40°C to

+85°C.
