ers active in the shutdown mode, unless dis-
abled 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.
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
0.1
μ
F 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
,
SP205
,
SP206
,
SP207B
,
SP211
and
SP213
models feature a low–power shut-
down mode, which reduces power supply drain
to 1
μ
A. The WakeUp function keeps the receiv-
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
