external (DE = 0) driver. A weak internal pull-up removes
the need for an external pull-up resistor if fast rise times
are not important. Several LTC1482s can share the same
CD line. CD = 1 forces RO to the high fail-safe state. In
shutdown, CD is three-stated. This pin can be pulled above
V
CC
but should not be taken above 8V to avoid damage.
DE (Pin 3):
Driver Enable Input. DE = 0 disables or three-
states the driver outputs. DE = 1 enables the driver outputs
with the high/low state of the outputs set by DI/SHDN.
DI/SHDN (Pin 4):
Driver Input and Shutdown Input. It is
used together with the DE pin to put the part in shutdown

RO (Pin 1):
Receiver Output. If a carrier is present (CD low)
and the part is not in shutdown, RO is high if the receiver
input differential voltage (A – B)
≥
V

and low if
(A – B)
≤

THRO(MIN)
. RO is forced to high (fail-safe state)
if a carrier is not present (CD = 1). In shutdown, RO is
three-stated. If the driver is enabled, RO follows the logic
level at the driver input.
CD (Pin 2):
Open-Drain Carrier Detect Output. Provided
that the part is not in shutdown, the CD output is low if
