SHUTDOWN MODE
The
SP200
,
SP205
,
SP205B
,
SP206
,
SP206B
,
SP207B
,
SP211
,
SP211B
and
SP213
all feature
a control input which will disable the device and
reduce the power supply current to less than
10
μ
A, making the parts ideal for battery–pow-
ered systems. In the “shutdown” mode the re-
ceivers and transmitters will both be tri–stated.
The V
+
output of the charge pump will discharge
to V
, and the V
–
output will discharge to
ground. Products with the WakeUp function can
enable or disable the receivers during shutdown.
For complete shutdown to occur and the 10
μ
A
power drain to be realized, the following condi-
tions must be met:
SP200
,
SP205/B
,
SP206/B
,
SP207B
and
SP211/B
:
+5V must be applied to the SD pin
ENABLE must be either 0V, +5.0V or not
connected
the transmitter inputs must be either +5.0V
or not connected
V
CC
must be +5V
Receiver inputs must be >0V and <+5V
SP213
:
0V must be applied to the SD pin
ENABLE must be either 0V, +5.0V or not
connected
the transmitter inputs must be either +5.0V
or not connected
V
CC
must be +5V
Receiver inputs must be >0V and <+5V
WAKEUP FUNCTION
The
SP205B
,
SP206B
,
SP207B
,
SP211B
and
SP213
have a wake–up feature that keeps two or
more receivers in an enabled state when the
device is in the shutdown mode. The
SP213
has
two receivers active (R
and R
), while the
SP205B
,
SP207B
and
SP211B
have all receiv-
ers active during shutdown. With only the re-
ceivers active during shutdown, the devices
draw 5–10
μ
A of supply current.
ENABLE
The
SP205/B
,
SP206/B
,
SP207/B
,
SP211
and
SP213
all feature an enable input, which allows
the receiver outputs to be either tri–stated or
enabled. This can be especially useful when the
receiver is tied directly to a microprocessor data
bus. For the
SP205/B
,
SP206/B
,
SP207/B
and
SP211
, enable is active low; that is, 0V applied
to the ENABLE pin will enable the receiver
outputs. For the
SP213
, enable is active high;
that is, +5V applied to the ENABLE pin will
enable the receiver outputs.
