±15kV ESD-Protected +2.5V to +5.5V
RS-232 Transceivers in UCSP and WLP
General Description
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
CC
range, V
L
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.
