:
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 lead to low output drive
levels and erratic charge pump operation.
GND:
Ground Pin.
ON/OFF:
A TTL/CMOS logic low puts the device in the low
power shutdown mode. All of the drivers and four receiv-
ers go to a high impedance state. Receiver RX5 remains
active while the transceiver is in shutdown. The trans-
ceiver consumes only 60
μ
A of supply current while in
shutdown. A logic high fully enables the transceiver.
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 receivers remain active
under these conditions. Floating the driver disable pin or
driving it to a logic low level fully enables the transceiver.
Supply current drops to 3mA when in driver disable mode.
A logic low on the ON/OFF pin supersedes the state of the
DRIVER DISABLE pin.

. Larger value
capacitors may be used to reduce supply ripple. With
multiple transceivers, the V

leled into common capacitors. For large numbers of
transceivers, increasing the size of the storage capaci-
tors is recommended to reduce ripple.
