DATASHEET ISL32172E, ISL32272E, ISL32372E, ISL32174E, ISL32274E, FN6824 Rev 2.00 ISL32374E, ISL32179E August 13, 2015 The Intersil ISL32x7xE are 16.5kV IEC61000-4-2 ESD Features Protected, 3.0V to 5.5V powered, QUAD transmitters for IEC61000 ESD protection on RS-422 outputs 16.5kV balanced communication using the RS-422 standard. These - Class 3 ESD level on all other pins . 12kV HBM drivers have very low output leakage currents (10A), so - High machine model ESD level on all pins 700V they present a low load to the RS-422 bus. Wide supply range 3.0V to 5.5V Driver (Tx) outputs are tri-statable, and incorporate a hot Specified for +125C operation plug feature to keep them disabled during power-up and down. Versions are available with a common EN/EN Available in industry standard pinouts (172/174) or in a space saving QFN (ISL32179E) with added features (172 pinout), a two channel EN12/EN34 (174 pinout), or a versatile combination of individual and group channel Logic supply pin (V ) eases operation in mixed supply L enables (see Table 1). systems (ISL32179E only) User selectable data rate (ISL32179E only) The ISL32372E, ISL32374E utilize slew rate limited drivers which reduce EMI and minimize reflections from improperly Hot plug - Tx outputs remain three-state during power-up terminated transmission lines, or from unterminated stubs in and power-down multidrop and multipoint applications. Drivers on the other Low Tx leakage allows > 256 devices on the bus versions are not limited, so they can achieve the 10Mbps or High data rates up to 32Mbps 32Mbps data rates. All versions are offered in industrial and Low quiescent supply current 0.8mA (max) extended industrial (-40C to +125C) temperature ranges. - Low shutdown supply current 60A A 50% smaller footprint (compared to the TSSOP) is Current limiting and thermal shutdown for driver overload available with the ISL32179Es QFN package. This device protection also features a logic supply pin (V ), that sets the switching L Tri-statable Tx outputs points of the enable and DI inputs to be compatible with a 5V tolerant logic inputs when V 5V lower supply voltage in mixed voltage systems. Two speed CC select pins allow the ISL32179E user to select from three Pb-free (RoHS compliant) slew rate options for 460kbps, 10Mbps, or 32Mbps data rates. Individual channel and group enable pins increase the Applications ISL32179Es flexibility.
