FEATURES…
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
0.1µF charge pump capacitors saves board space
and reduces circuit cost. Different models within
the Series provide different driver/receiver com-
binations to match any application requirement.
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

the shutdown mode, unless disabled by the EN
pin. Models with a “B” suffix are equipped with
the WakeUp function.
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-
pared to older less–efficient designs. The charge
pump still requires four external capacitors, but
uses a four–phase voltage shifting technique to
