The MAX3228E/AE and MAX3229E/AE are +2.5V to

+5.5V powered EIA/TIA-232 and V.28/V.24 communica-

tions interfaces with low power requirements, high data-

rate capabilities, and enhanced electrostatic discharge

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

and WLP Package. All transmitter outputs and receiver

inputs are protected 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/AE and MAX3229E/AE achieve a 1µA

supply current 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 transmitters 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/AE and MAX3229E/AE offer a separate

power-supply input for the logic interface, allowing con-

figurable logic levels on the receiver outputs and trans-

mitter inputs. Operating over a +1.65V to V

provides the MAX3228E/AE and MAX3229E/AE com-

patibility with multiple logic families.

The MAX3229E/AE contains one receiver and one

transmitter. The MAX3228E/AE contains two receivers

and two transmitters. The MAX3228E/AE and

MAX3229E/AE are available in tiny chip-scale and WLP

packaging and are specified across the extended

industrial temperature range of -40°C to +85°C.
