FN6048.7

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

High Speed or Slew Rate Limited,

RS-485/RS-422 Transceivers

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).

Features

• Pb-Free Plus Anneal Available (RoHS Compliant)

• 125°C Temperature Option

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

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

• Specified for 10% Tolerance Supplies

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

• Slew Rate Limited Version for Error Free Data

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

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.

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

• 1nA Low Current Shutdown Mode (ISL8483E)

• Low Quiescent Current:

- 160µA (ISL8483E)

- 500µA (ISL8485E)

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.

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

• Three State Rx and Tx Outputs

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

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

floating.

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

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

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.

• Current Limiting and Thermal Shutdown for driver

Overload Protection

Applications

• Factory Automation

These half duplex configurations multiplex the Rx inputs and

Tx outputs to allow transceivers with Rx and Tx disable

functions in 8 lead packages.

• Security Networks

• Building Environmental Control Systems

• Industrial/Process Control Networks

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

• RS-232 “Extension Cords”
