+2.5V to +5.5V RS-232 Transceivers
in UCSP
General Description
The MAX3228/MAX3229 are +2.5V to +5.5V powered
EIA/TIA-232 and V.28/V.24 communications interfaces
with low power requirements, and high data-rate capa-
bilities, in a chip-scale package (UCSP™).
The MAX3228/MAX3229 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 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 MAX3228/MAX3229 offer a separate power-supply
input for the logic interface, allowing configurable logic
levels on the receiver outputs and transmitter inputs.
Operating over a +1.65V to V
CC
range, V
L
provides the
MAX3228/MAX3229 compatibility with multiple logic
families.
The MAX3229 contains one receiver and one transmit-
ter. The MAX3228 contains two receivers and two
transmitters. The MAX3228/MAX3229 are available in
tiny chip-scale packaging and are specified across the
extended industrial temperature range of -40°C to
+85°C.
