VCC: 5V Input Supply Pin. This pin should be decoupled
with a 0.1F ceramic capacitor.
GND: Ground Pin.
V+: Positive Supply Output (RS232 Drivers). V+ 2VCC –
2V. This pin requires an external capacitor C = 0.1F for
charge storage. The capacitor may be tied to ground or
VCC. With multiple devices, the V + and V – pins may share
a common capacitor. For large numbers of devices, in-
creasing the size of the shared common storage capaci-
tors is recommended to reduce ripple.
V–: Negative Supply Output (RS232 Drivers). V – – (2VCC
– 2V). This pin requires an external capacitor C = 0.1F for
charge storage.
C1+, C1–, C2+, C2–: Commutating Capacitor Inputs. These
pins require two external capacitors C = 0.1F: one from
C1+ to C1– and another from C2+ to C2 –. To maintain
charge pump efficiency, the capacitor’s effective series
resistance should be less than 2.
TR IN: RS232 Driver Input Pins. Inputs are TTL/CMOS
compatible. The inputs of unused drivers can be left
unconnected since 300k input pull-up resistors to VCC are
included on chip.
TR OUT: Driver Outputs at RS232 Voltage Levels. The
driver outputs are protected against ESD to ±10kV for
human body model discharges.
RX IN: Receiver Inputs. These pins can be forced to ±25V
without damage. The receiver inputs are protected against
ESD to ±10kV for human body model discharges. Each
receiver provides 0.4V of hysteresis for noise immunity.
RX OUT: Receiver Outputs with TTL/CMOS Voltage
Levels.
