With multiple devices, the V + and V – pins may be paral-
leled into common capacitors. For large numbers of de-
vices, increasing the size of the shared common storage
capacitors is recommended to reduce ripple.
V–: Negative Supply Output (RS232 Drivers). V – 2VCC –
1.5V. 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
+ to C1–, and another from C2+ to C2–. To maintain
charge pump efficiency, the capacitor’s effective series
resistance should be less than 20.

VCC: 5V Input Supply Pin. Supply current is typically 35A
in the Shutdown mode. This pin should be decoupled with
a 0.1F ceramic capacitor.
GND: Ground Pin.
ON/OFF: TTL/CMOS Compatible Shutdown Pin. A logic
low puts the device in Shutdown mode, with receivers 4
and 5 kept alive and the supply current equal to 35A. All
driver outputs and other receiver outputs are in high
impedance state. This pin can not float.
V+: Positive Supply Output (RS232 Drivers). V+ 2VCC –
1V. This pin requires an external capacitor C = 0.1F for
charge storage. The capacitor may be tied to ground or 5V.
