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