Data Sheet

FN6048.3

ESD Protected to ±15kV, 5V, Low Power,

High Speed or Slew Rate Limited,

RS-485/RS-422 Trans ceivers

Features

• RS-485 I/O Pin ESD Protection . . . . . . . . . . . . . ±15kV HBM

- Class 3 ESD Level on all Other Pins . . . . . . >7kV HBM

• Specified for 10% Tolerance Supplies

These Intersil RS-485/RS-422 devices are ESD protected,

BiCMOS 5V powered, single transceivers that meet both the

RS-485 and RS-422 standards for balanced communication.

Each driver output/receiver input is protected against ±15kV

ESD strikes, without latch-up. Unlike competitive devices,

this Intersil family is specified for 10% tolerance supplies

(4.5V to 5.5V).

• High Data Rate Version (ISL8485E) . . . . . . up to 5Mbps

• Slew Rate Limited Version for Error Free Data

Transmission (ISL8483E) . . . . . . . . . . . . . .up to 250kbps

• Single Unit Load Allows up to 32 Devices on the Bus

• 1nA Low Current Shutdown Mode (ISL8483E)

The ISL8483E utilizes slew rate limited drivers which reduce

EMI, and minimize reflections from improperly terminated

transmission lines, or unterminated stubs in multidrop and

multipoint applications.

• Low Quiescent Current:

- 160µA (ISL8483E)

- 340µA (ISL8485E)

• -7V to +12V Common Mode Input Voltage Range

• Three State Rx and Tx Outputs

Data rates up to 5Mbps are achievable by using the

ISL8485E which features higher slew rates.

Both devices present a “single unit load” to the RS-485 bus,

which allows up to 32 transceivers on the network.

• 30ns Propagation Delays, 5ns Skew (ISL8485E)

• Operate from a Single +5V Supply (10% Tolerance)

Receiver (Rx) inputs feature a “fail-safe if open” design,

which ensures a logic high Rx output, if Rx inputs are

floating.

• Current Limiting and Thermal Shutdown for driver

Overload Protection

Applications

Driver (Tx) outputs are short circuit protected, even for

voltages exceeding the power supply voltage. Additionally,

on-chip thermal shutdown circuitry disables the Tx outputs to

prevent damage if power dissipation becomes excessive.

• Factory Automation

• Security Networks

• Building Environmental Control Systems

• Industrial/Process Control Networks

• Level Translators (e.g., RS-232 to RS-422)

• RS-232 “Extension Cords”

These half duplex configurations multiplex the Rx inputs and

Tx outputs to allow transceivers with Rx and Tx disable

functions in 8 lead packages.
