Data Sheet

FN6543.2

±16.5kV ESD Protected, +125°C, 3.0V to

5.5V, SOT-23/TDFN Packaged, 20Mbps,

Full Fail-safe, Low Power, RS-485/RS-422

Receivers

Features

• IEC61000 ESD Protection on RS-485 Inputs . . . ±16.5kV

- Class 3 ESD Level on all Other Pins . . . . . . >5kV HBM

• Pb-Free (RoHS Compliant)

The Intersil ISL3280E, ISL3281E, ISL3282E, ISL3283E,

ISL3284E, ISL3285E are ±16.5kV IEC61000 ESD

Protected, 3.0V to 5.5V powered, single receivers that meet

both the RS-485 and RS-422 standards for balanced

communication. These receivers have very low bus currents

(+125µA/-100µA), so they present a true “1/8 unit load” to the

RS-485 bus. This allows up to 256 receivers on the network

without violating the RS-485 specification’s 32 unit load

maximum and without using repeaters.

• Wide Supply Range . . . . . . . . . . . . . . . . . . . 3.0V to 5.5V

• Specified for +125°C Operation

• Logic Supply Pin (V ) Eases Operation in Mixed Supply

Systems (ISL3282E, ISL3284E, ISL3285E Only)

• Full Fail-safe (Open, Short, Terminated/Undriven)

• True 1/8 Unit Load Allows up to 256 Devices on the Bus

• High Data Rates. . . . . . . . . . . . . . . . . . . . . up to 20Mbps

Receiver inputs feature a “Full Fail-Safe” design, which

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

shorted, or terminated but undriven.

• Low Quiescent Supply Current . . . . . . . . . . 500µA (Max)

- Very Low Shutdown Supply Current. . . . . . 20µA (Max)

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

The ISL3280E and ISL3284E feature an always enabled Rx;

the ISL3281E and ISL3285E feature an active high Rx

enable pin, and the ISL3282E and ISL3283E include an

active low enable pin. All versions are offered in Industrial

and Extended Industrial (-40°C to +125°C) temperature

ranges.

• Tri-statable Rx Available (Active Low or High EN Input)

• 5V Tolerant Logic Inputs When V

≤ 5V

Applications

• Clock Distribution

A 26% smaller footprint is available with the ISL3282E and

ISL3285E TDFN package. These devices, plus the

• High Node Count Systems

• Space Constrained Systems

• Security Camera Networks

ISL3284E, also feature a logic supply pin (V ) that sets the

level of the RO output (and the switching points of the

RE / RE input) to be compatible with another supply voltage

in mixed voltage systems.

• Building Environmental Control/Lighting Systems

• Industrial/Process Control Networks

For companion single RS-485 transmitters in micro

packages, please see the ISL3293E, ISL3294E, ISL3295E,

ISL3296E, ISL3297E, ISL3298E data sheet.
