Data Sheet

December 2003

FN6052.2

3.3V, Low Power, High Speed or Slew

Features

Rate Limited, RS-485/RS-422 Trans ceivers

• Operate from a Single +3.3V Supply (10% Tolerance)

• Interoperable with 5V Logic

These Intersil RS-485/RS-422 devices are BiCMOS 3.3V

powered, single transceivers that meet both the RS-485 and

RS-422 standards for balanced communication. Unlike

competitive devices, this Intersil family is specified for 10%

tolerance supplies (3V to 3.6V).

• High Data Rates. . . . . . . . . . . . . . . . . . . . . up to 10Mbps

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

• Slew Rate Limited Versions for Error Free Data

The ISL83483 and ISL83488 utilize slew rate limited drivers

which reduce EMI, and minimize reflections from improperly

terminated transmission lines, or unterminated stubs in

multidrop and multipoint applications.

Transmission (ISL83483, ISL83488) . . . . . .up to 250kbps

• Low Current Shutdown Mode (ISL83483, ISL83485,

ISL83491). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .15nA

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

Data rates up to 10Mbps are achievable by using the

ISL83485, ISL83490, or ISL83491, which feature higher

slew rates.

• Three State Rx and Tx Outputs (Except ISL83488,

ISL83490)

• 10ns Propagation Delay, 1ns Skew (ISL83485, ISL83490,

ISL83491)

Logic inputs (e.g., DI and DE) accept signals in excess of

5.5V, making them compatible with 5V logic families.

• Full Duplex and Half Duplex Pinouts

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

which ensures a logic high output if Rx inputs are floating. All

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

allows up to 32 transceivers on the network.

• 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”

The ISL83488, ISL83490, ISL83491 are configured for full

duplex (separate Rx input and Tx output pins) applications.

The ISL83488 and ISL83490 are offered in space saving 8

lead packages for applications not requiring Rx and Tx

output disable functions (e.g., point-to-point and RS-422).

Half duplex configurations (ISL83483, ISL83485) multiplex

the Rx inputs and Tx outputs to provide transceivers with Rx

and Tx disable functions in 8 lead packages.
