Fault Protected, Extended CMR, RS-485/RS-422

Transceivers with Cable Invert

ISL31480E, ISL31483E, ISL31485E, ISL31486E

The ISL3148xE are fault protected, 5V powered

differential transceivers that exceed the RS-485 and

Features

• Fault Protected RS-485 Bus Pins. . . . . . up to ±60V

• Extended Common Mode Range. . . . . . . . . . ±25V

More Than Twice the Range Required for RS-485

• Cable Invert Pins (Except ISL31480)

Corrects for Reversed Cable Connections While

Maintaining Rx Full Fail-safe Functionality

RS-422 standards for balanced communication. The

RS-485 transceiver pins (driver outputs and receiver

inputs) are protected against faults up to ±60V.

Additionally, the extended common mode range allows

these transceivers to operate in environments with

common mode voltages up to ±25V (>2X the RS-485

requirement), making this RS-485 family one of the

most robust on the market.

• Logic Supply (V ) Pin (ISL31480E, ISL31486E)

Simplifies Interface to Lower Voltage Logic Devices

Transmitters deliver an exceptional 2.5V (typical)

differential output voltage into the RS-485 specified 54Ω

load. This yields better noise immunity than standard

RS-485 ICs, or allows up to six 120Ω terminations in star

network topologies.

• Full Fail-safe (Open, Short, Terminated) RS-485

Receivers

• 1/4 Unit Load (UL) for up to 128 Devices on the Bus

• High Rx I

for Opto-Couplers in Isolated Designs

• Hot Plug Circuitry - Tx and Rx Outputs Remain

Three-State During Power-up/Power-down

• Slew Rate Limited RS-485 Data Rate . . . . . . 1Mbps

• Low Quiescent Supply Current . . . . . . . . . . . 2.3mA

Ultra Low Shutdown Supply Current . . . . . . . . 10µA

Receiver (Rx) inputs feature a “Full Fail-Safe” design,

which ensures a logic high Rx output if Rx inputs are

floating, shorted, or on a terminated but undriven (idle)

bus.

The ISL31483E, ISL31485E and ISL31486E include cable

invert functions that reverse the polarity of the Rx and/or

Tx bus pins in case the cable is misconnected. Unlike

competing devices, Rx full fail-safe operation is

Applications*(see page 19)

• Utility Meters/Automated Meter Reading Systems

• High Node Count Systems

maintained even when the Rx input polarity is switched.

• PROFIBUS® and Field Bus Networks, and Factory

Automation

• Security Camera Networks

• Building Lighting and Environmental Control Systems

• Industrial/Process Control Networks

The ISL31480E and ISL31486E feature a logic supply

(V ) pin that sets the V

of the Rx outputs, and the

switching points of the logic input pins, to be compatible

with a lower supply voltage (down to 1.8V) in mixed

voltage systems. See Table 1 on page 2 for key features

and configurations by device number.
