Receivers
The receivers convert RS-232 input signals to
inverted TTL signals. Since the input is usually
from a transmission line where long cable lengths
and system interference can degrade the signal,
the inputs have a typical hysteresis margin of
500mV. This ensures that the receiver is virtu-
ally immune to noisy transmission lines. Should
an input be left unconnected, a 5k
pulldown
resistor to ground will commit the output of the
receiver to a high state.
SHUTDOWN MODE
The
SP211E,
and
SP213E
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–powered
systems. In the “shutdown” mode the receivers
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 Wake-Up 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
conditions must be met:
SP211E:
+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
SP213E:
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
