CC
:
5V Input Supply Pin. This pin should be decoupled
with a 0.1
μ
F ceramic capacitor close to the package pin.
Insufficient supply bypassing can result in low output
drive levels and erratic charge pump operation.
V
L
:
3V Logic Supply Pin. Provides power to the receiver
outputs. Decouple with a 0.1
μ
F ceramic capacitor.
GND:
Ground Pin.
ON/OFF:
A TTL/CMOS Compatible Operating Mode Con-
trol. A logic low puts the device in the low power shutdown
mode. Drivers and receivers assume a high impedance
state in shutdown. The transceiver consumes almost no
supply current while in shutdown. A logic high fully
enables the transceiver. An ON/OFF logic low signal super-
sedes the state of the DRIVER DISABLE pin.
U
DRIVER DISABLE:
This pin provides an alternate control
for the charge pump and RS232 drivers. A logic high on
this pin shuts down the charge pump and places all drivers
in a high impedance state. All five receivers remain active
under these conditions. Floating the DRIVER DISABLE pin
or driving it to a logic low level fully enables the trans-
ceiver. A logic low on the ON/OFF pin supersedes the state
of the DRIVER DISABLE pin. Supply current drops to 3mA
when in driver disable mode.

tor C
≥

μ
F, tied to ground or V
CC
. With multiple
transceivers, the V
+
and V
–
pins may be paralleled into
common charge storage capacitors. Larger value capaci-
tors may be used to reduce supply ripple.
