Data Sheet  
September 15, 2005  
FN6051.6  
±15kV ESD Protected, 1/8 Unit Load, 5V,  
Low Power, High Speed or Slew Rate  
Limited, RS-485/RS-422 Transceivers  
Features  
• RS-485 I/O Pin ESD Protection . . . . . . . . . . ±15kV HBM  
- Class 3 ESD Level on all Other Pins . . . . . . >7kV HBM  
These Intersil RS-485/RS-422 devices are ESD protected,  
fractional unit load (UL), 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).  
• Fractional Unit Load Allows up to 256 Devices on the Bus  
• Specified for 10% Tolerance Supplies  
• High Data Rate Version (ISL81487E) . . . . . up to 5Mbps  
• Slew Rate Limited Versions for Error Free Data  
Transmission (ISL8487E, ISL81487L) . . . . .up to 250kbps  
• Low Current Shutdown Mode (Except ISL81487E). . . 0.5µA  
All devices present a 1/8 “unit load” to the RS-485 bus,  
which allows up to 256 transceivers on the network for large  
node count systems (e.g., process automation, remote  
meter reading systems). In a remote utility meter reading  
system, individual (apartments for example) utility meter  
readings are routed to a concentrator via an RS-485  
network, so the high allowed node count minimizes the  
number of repeaters required to network all the meters. Data  
for all meters is then read out from the concentrator via a  
single access port, or a wireless link.  
• Low Quiescent Supply Current:  
- ISL8487E, ISL81487L . . . . . . . . . . . . . . . 145µA (Max.)  
- ISL81487E . . . . . . . . . . . . . . . . . . . . . . . . 420µA (Max.)  
• -7V to +12V Common Mode Input Voltage Range  
• Three State Rx and Tx Outputs  
• 30ns Propagation Delays, 5ns Skew (ISL81487E)  
• Half Duplex Pinouts  
• Operate from a Single +5V Supply (10% Tolerance)  
Slew rate limited drivers on the ISL8487E and ISL81487L  
reduce EMI, and minimize reflections from improperly  
terminated transmission lines, or unterminated stubs in  
multidrop and multipoint applications. Data rates up to  
250kbps are achievable with these devices.  
• Current Limiting and Thermal Shutdown for Driver  
Overload Protection  
• Pin Compatible Replacements for: MAX487E, (ISL8487E);  
LTC1487, ADM1487 (ISL81487L); MAX1487E, ST485ER  
(ISL81487E)  
Data rates up to 5Mbps are achievable by using the  
ISL81487E, which features higher slew rates.  
• Pb-Free Plus Anneal Available (RoHS Compliant)  
Receiver (Rx) inputs feature a “fail-safe if open” design,  
which ensures a logic high Rx output if Rx inputs are floating.  
Applications  
• High Node Count Networks  
• Automated Utility Meter Reading Systems  
• 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.  
• Security Networks  
These half duplex devices multiplex the Rx inputs and Tx  
outputs to allow transceivers with Rx and Tx disable  
functions in 8 lead packages.  
• Building Environmental Control Systems  
• Industrial/Process Control Networks
