Data Sheet

FN6060.2

5V, Ultra High Speed, PROFIBUS®,

RS-485/RS-422 Transceivers

Features

• Specified for 10% Tolerance Supplies

The Intersil ISL4486 and ISL81486 are BiCMOS, 5V

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

RS-422 standards for balanced communication, and feature

the larger output voltage and higher data rate - up to

40Mbps - required by high speed PROFIBUS applications.

• High Data Rates

ISL4486 . . . . . . . . . . . . . . . . . . . . . . . . . . up to 40Mbps

ISL81486 . . . . . . . . . . . . . . . . . . . . . . . . . up to 30Mbps

• Large Differential Output Voltage . . . . . . . . . . 3V into 54Ω

• Low Bit-to-Bit (Part-to-Part) Skew for Parallel Applications

• 0.6 Unit Load Allows up to 50 Devices on the Bus

• ISL81486 is a Drop-In Replacement for the ADM1486

• Low Quiescent Current . . . . . . . . . . . . . . . . . . . . . 800µA

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

• Three-State Rx and Tx Outputs

Unlike competitive products, these Intersil devices are

specified for 10% tolerance supplies (4.5V to 5.5V) and

deliver at least a 2.3V differential output voltage over this

supply range. At the 5% tolerance specified by many

competitors, the ISL4486 delivers an unsurpassed 2.5V

differential signal into a 54Ω total load. This translates into

longer reach, or better data integrity, at the exceptional

40Mbps data rate.

• 14ns (Max) Propagation Delays, 2ns (Max) Skew

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

SCSI applications benefit from the ISL4486’s low receiver

and transmitter part-to-part skews, which make it perfect for

high speed parallel applications where large numbers of bits

must be simultaneously captured. The low bit-to-bit skew

eases the timing constraints on the data latching signal.

• Current Limiting and Thermal Shutdown for driver

Overload Protection

• Pb-free available

These devices present a “0.6 unit load” to the RS-485 bus,

which allows up to 50 transceivers on the network.

Applications

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

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

• SCSI “Fast 40” Drivers and Receivers

• PROFIBUS DP and FMS Networks

• Factory Automation

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.

• Field Bus Networks

• Security Networks

• Building Environmental Control Systems

• Industrial/Process Control Networks

*Add “-T” suffix to part number for tape and reel packaging.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding

compounds/die attach materials and 100% matte tin plate termination finish, which

is compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free

products are MSL classified at Pb-free peak reflow temperatures that meet or

exceed the Pb-free requirements of IPC/JEDEC J Std-020B.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
