QUAD, ±16.5kV ESD Protected, 3.0V
to 5.5V, Low Power, RS-422 Transmitters
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 (±10A), so
they present a low load to the RS-422 bus.
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).
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.
A 50% smaller footprint (compared to the TSSOP) is
available with the ISL32179E’s QFN package. This device
also features a logic supply pin (VL), that sets the switching
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.
