LTC1483

Ultra-Low Power RS485 Low EMI

Transceiver with Shutdown

DESCRIPTIO

EATURE

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

LTC1483featuresoutputdriverswithcontrolledslewrate,

decreasing the EMI radiated from the RS485 lines, and

improving signal fidelity with misterminated lines. The

CMOS design offers significant power savings over its

bipolarcounterpartswithoutsacrificingruggednessagainst

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

Low Power: I_CC= 120µA Max with Driver Disabled

I_CC= 500µA Max with Driver Enabled, No Load

1µA Quiescent Current in Shutdown Mode

Controlled Slew Rate Driver for Reduced EMI

Single 5V Supply

Drivers/Receivers Have ±10kV ESD Protection

–7V to 12V Common-Mode Range Permits ±7V

Ground Difference Between Devices on the Data Line

Thermal Shutdown Protection

Power Up/Down Glitch-Free Driver Outputs Permit

Live Insertion or Removal of Transceiver

Driver Maintains High Impedance in Three-State

or with the Power Off

■

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

inputsareleftopen. I/Opinsareprotectedagainstmultiple

ESD strikes of over ±10kV.
