Data Sheet  
December 16, 2008  
FN6824.0  
QUAD, ±16.5kV ESD Protected, 3.0V  
Features  
to 5.5V, Low Power, RS-422 Transmitters  
• IEC61000 ESD Protection on RS-422 Outputs . . ±16.5kV  
- Class 3 ESD Level on all Other Pins . . . . . . 12kV HBM  
- High Machine Model ESD Level on all Pins . . . . . 700V  
The Intersil ISL32x7xE are ±16.5kV IEC61000-4-2 ESD  
Protected, 3.0V to 5.5V powered, QUAD transmitters for  
balanced communication using the RS-422 standard. These  
drivers have very low output leakage currents (±10µA), so  
they present a low load to the RS-422 bus.  
• Wide Supply Range . . . . . . . . . . . . . . . . . . . 3.0V to 5.5V  
• Specified for +125°C Operation  
• Available in Industry Standard Pinouts (‘172/’174) or in a  
Space Saving QFN (ISL32179E) with Added Features  
Driver (Tx) outputs are tri-statable, and incorporate a hot  
plug feature to keep them disabled during power-up and  
down. Versions are available with a common EN/EN  
(‘172 pinout), a two channel EN12/EN34 (‘174 pinout), or a  
versatile combination of individual and group channel  
enables (see Table 1).  
• Logic Supply Pin (V ) Eases Operation in Mixed Supply  
L
Systems (ISL32179E Only)  
• User Selectable Data Rate (ISL32179E Only)  
• Hot Plug - Tx Outputs Remain Three-state During  
Power-up and Power-Down  
The ISL32372E, ISL32374E utilize slew rate limited drivers  
which reduce EMI, and minimize reflections from improperly  
terminated transmission lines, or from unterminated stubs in  
multidrop and multipoint applications. Drivers on the other  
versions are not limited, so they can achieve the 10Mbps or  
32Mbps data rates. All versions are offered in Industrial and  
Extended Industrial (-40°C to +125°C) temperature ranges.  
• Low Tx Leakage Allows > 256 Devices on the Bus  
• High Data Rates. . . . . . . . . . . . . . . . . . . . . up to 32Mbps  
• Low Quiescent Supply Current . . . . . . . . . . 0.8mA (Max)  
- Low Shutdown Supply Current. . . . . . . . . . . . . . . 60µA  
• Current Limiting and Thermal Shutdown for Driver  
Overload Protection  
A 50% smaller footprint (compared to the TSSOP) is  
available with the ISL32179E’s QFN package. This device  
• Tri-statable Tx Outputs  
also features a logic supply pin (V ), that sets the switching  
L
points of the enable and DI inputs to be compatible with a  
lower supply voltage in mixed voltage systems. Two speed  
select pins allow the ISL32179E user to select from three  
slew rate options for 460kbps, 10Mbps, or 32Mbps data  
rates. Individual channel and group enable pins increase the  
ISL32179E’s flexibility.  
• 5V Tolerant Logic Inputs When V  
• Pb-free (RoHS compliant)  
≤ 5V  
CC  
Applications  
• Telecom Equipment  
• Motor Controllers / Encoders  
• Programmable Logic controllers
