LTC1482

Low Power RS485 Transceiver

with Carrier Detect and

Receiver Fail-Safe

DESCRIPTIO

The LTC

1482 is a low power RS485 compatible trans-

ceiver that offers an active low carrier detect output. The

open-drain carrier detect pin allows several transceivers

to share the same carrier detect line and can be used to

detect the insertion or removal of a driven RS485/RS422

cable.

Enhanced ESD protection allows the LTC1482 to with-

stand

±15kV

(human body model), IEC-1000-4-2 level 4

(±8kV) contact and level 3 (±8kV) air discharge ESD

without latchup or damage.

The LTC1482 receiver stays alive at all times except in

shutdown. The supply current is a maximum of 700µA

and 900µA when the driver is disabled and enabled

respectively. In shutdown, the quiescent current of the

LTC1482 drops to a maximum of 20µA.

When the driver is disabled or the LTC1482 is in shut-

down, the driver outputs are three-stated and remain in

a high impedance state over the RS485 common mode

range.

Excessive power dissipation caused by bus contention or

faults is prevented by a thermal shutdown circuit, which

forces the driver outputs into a high impedance state.

The LTC1482 is fully specified over the commercial and

industrial temperature ranges and is available in 8-lead

MSOP, PDIP and SO packages.
