The Intersil ISL32x7xE are В±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 (В±10ВµA), so
they present a low load to the RS-422 bus. FN6824
Rev 2.00
August 13, 2015 Features IEC61000 ESD protection on RS-422 outputs В±16.5kV
-Class 3 ESD level on all other pins . 12kV HBM
-High machine model ESD level on all pins 700V Wide supply range 3.0V to 5.5V 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). Specified for +125°C operation Available in industry standard pinouts (�172/’174) or in a
space saving QFN (ISL32179E) with added features Logic supply pin (VL) eases operation in mixed supply
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
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 …
