Pin Compatible with the LTC485

The LTC

1481 is an ultralow power differential line trans-

ceiver designed for data transmission standard RS485

applications. It will also meet the requirements of RS422.

The CMOS design offers significant power savings over its

bipolar counterparts without sacrificing ruggedness against

overload or ESD damage. Typical quiescent current is only

80µA while operating and less than 1µA in shutdown.

The driver and receiver feature three-state outputs, with

the driver outputs maintaining high impedance over the

entire 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 receiver has a fail-safe

feature which guarantees a high output state when the

inputs are left open.

The LTC1481 is fully specified over the commercial and

extended industrial temperature range and is available in

8-pin PDIP and SO packages.
