FEATURES…

pin. Models with a “B” suffix are equipped with
the WakeUp function.
The SP200 Series multi–channel RS-232 line
transceivers provide a variety of configurations
to fit most communication needs, especially
those applications where ±12V is not available.
All models in this Series feature low–power
CMOS construction and Sipex proprietary on-
board charge pump circuitry to generate the
±10V RS-232 voltage levels. The ability to use
0.1µFchargepumpcapacitorssavesboardspace
andreducescircuitcost.Differentmodelswithin
theSeriesprovidedifferentdriver/receivercom-
binations to match any application requirement.
Models in the Series are available in 28–pin SO
(wide) and SSOP (shrink) small outline pack-
ages. Devices can be specified for commercial
(0°C to +70°C) and industrial/extended (–40°C
to +85°C) operating temperatures.
THEORY OF OPERATION
Charge–Pump
The charge pump is a Sipex patented design
(5,306,954) and uses a unique approach com-
paredtoolderless–efficientdesigns.Thecharge
pump still requires four external capacitors, but
uses a four–phase voltage shifting technique to
The SP200, SP206, SP207B, SP211 and SP213
models feature a low–power shutdown mode,
which reduces power supply drain to 1µA. The
WakeUp function keeps the receivers active in
