Data Sheet  
July 2004  
FN6061.1  
5V, 30Mbps, RS-485/RS-422 Transceiver  
Features  
The Intersil ISL81485 is a BiCMOS, 5V powered, single  
transceiver that meets both the RS-485 and RS-422  
standards for balanced communication, and features a larger  
output voltage and higher data rate to benefit high speed  
applications.  
• Specified for 10% Tolerance Supplies  
• High Data Rates. . . . . . . . . . . . . . . . . . . . . up to 30Mbps  
• Large Differential Output Voltage . . . . 2.0V(min.) into 54Ω  
• Drop-In Replacement for the ADM1485  
Unlike competitive devices, this Intersil transceiver is  
specified for 10% tolerance supplies (4.5V to 5.5V), and it  
delivers a much larger worst case differential output voltage  
(2.0V compared to the typical 1.5V) over the full supply  
range. The increased output voltage translates into longer  
reach, or better data integrity, at the 30Mbps data rate.  
• One Unit Load Allows up to 32 Devices on the Bus  
• Low Quiescent Current . . . . . . . . . . . . . . . . . . . . . 800µA  
• -7V to +12V Common Mode Input Voltage Range  
• Three State Rx and Tx Outputs  
• 15ns (Max) Propagation Delays, 5ns (Max) Skew  
• Operates from a Single +5V Supply (10% Tolerance)  
This device presents a “1 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  
Receiver (Rx) inputs feature a “fail-safe if open” design,  
which ensures a logic high Rx output if Rx inputs are  
floating.  
• Pb-free available  
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.  
Applications  
• SCSI “Fast 20” Drivers and Receivers  
• Factory Automation  
• Field Bus Networks

• Security Networks

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.
