Pin Compatible with the LTC485

The LTC

1483 is an ultra-low power differential line trans-

ceiver designed for data transmission standard RS485

applications with extended common-mode range (– 7V to

12V). It will also meet the requirements of RS422. The

LTC1483 features output drivers with controlled slew rate,

decreasing the EMI radiated from the RS485 lines, and

improving signal fidelity with misterminated lines. 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. I/O pins are protected against multiple

ESD strikes of over

±10kV.

The LTC1483 is fully specified over the commercial and

extended industrial temperature range and is available in

8-pin DIP and SO packages.
