The LTC

1480 is an ultralow power differential line trans-

ceiver which provides full RS485 compatibility while oper-

ating from a single 3.3V supply. It is designed for data

transmission standard RS485 applications with extended

common mode range (12V to –7V). It also meets the

requirements of RS422 and features high speed operation

up to 2.5Mb/s. The CMOS design offers significant power

savings without sacrificing ruggedness against overload

or ESD damage. Typical quiescent current is only 300µA

while operating and 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 LTC1480 is fully specified over the commercial and

extended industrial temperature range. The LTC1480 is

available in 8-pin SO and DIP packages.
