Description
1
NC
No Connect. This pin should always remain unconnected.
2, 3
VCC
Power Supply Input. A 0.1 F decoupling capacitor is required between VCC and ground. When a voltage
between 4.5 V and 5.5 V is applied to the VCC pin, the integrated dc-to-dc converter is enabled. If this voltage
is lowered to between 3.0 V and 3.7 V, the integrated dc-to-dc converter is disabled.
4, 5, 6, 7, 10
GND
Ground.
8
ROUT
Receiver Output. This pin outputs CMOS logic levels.
9
TIN
Transmitter (Driver) Input. This pin accepts CMOS levels.
11
GNDISO
Ground Reference for Isolated RS-232 Side.
12
V
Internally Generated Negative Supply.
13, 14
C2, C2+
Positive and Negative Connections for Charge Pump Capacitors. External Capacitor C2 is connected between
these pins; a 0.1 F capacitor is recommended, but larger capacitors up to 10 F can be used.
15
RIN
Receiver Input. This input accepts RS-232 signal levels.
16
TOUT
Transmitter (Driver) Output. This outputs RS-232 signal levels.
17, 18
C1, C1+
Positive and Negative Connections for Charge Pump Capacitors. External Capacitor C1 is connected between
these pins; a 0.1 F capacitor is recommended, but larger capacitors up to 10 F can be used.
19
V+
Internally Generated Positive Supply.
20
VISO
Isolated Supply Voltage for Isolator Secondary Side. A 0.1 F decoupling capacitor is required between VISO
and ground. When the integrated dc-to-dc converter is enabled, the VISO pin should not be used to power
external circuitry. If the integrated dc-to-dc converter is disabled, power the secondary side by applying a
voltage in the range of 3.0 V to 5.5 V to this pin.
