Pin Descriptions
V
V+ (Pin 1). Positive supply for TIA/EIA-232-E drivers. Rec-
ommended external capacitor — 0.47 µF (16V). This supply
is not intended to be loaded externally.
V− (Pin 25). Negative supply for TIA/EIA-232-E drivers.
Recommended external capacitor — 0.47 µF (16V). This
supply is not intended to be loaded externally.
C1+, C1− (Pins 6, 24). External capacitor connection pins.
Recommended capacitor — 0.47 µF (6.3V).
C2+, C2− (Pins 2, 4). External capacitor connection pins.
Recommended capacitor — 0.47 µF (16V).
CC
(Pin 3). Power supply pin for the device, +3.3V (

C3+, C3− (Pins 28, 26). External capacitor connection pins.
Recommended capacitor — 0.47 µF (6.3V).
SHUTDOWN (SD) (Pin 23). A High on the SHUTDOWN pin
will lower the total I
low power state. In this mode receiver R5 remains active.
The SD pin should be driven or tied low (GND) to disable the
shutdown mode.
