±16.5kV ESD Protected, +125°C, 3.0V to
5.5V, SOT-23/TDFN Packaged, Low Power,
RS-485/RS-422 Transmitters
The Intersil ISL3293E, ISL3294E, ISL3295E, ISL3296E,
ISL3297E, ISL3298E are ±16.5kV HBM ESD Protected (7kV
IEC61000 contact), 3.0V to 5.5V powered, single
transmitters for balanced communication using the RS-485
and RS-422 standards. These drivers have very low bus
currents (±40mA), so they present less than a “1/8 unit load”
to the RS-485 bus. This allows more than 256 transmitters on
the network without violating the RS-485 specification’s
32 unit load maximum, and without using repeaters.
Hot Plug circuitry ensures that the Tx outputs remain in a
high impedance state while the power supply stabilizes.
The ISL3293E, ISL3294E, ISL3296E, ISL3297E 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 ISL3295E and ISL3298E are not limited, so they
can achieve the 20Mbps data rate. All versions are offered in
Industrial and Extended Industrial (-40°C to +125°C)
temperature ranges.
A 26% smaller footprint is available with the ISL3296E,
ISL3297E, ISL3298E’s TDFN package. These devices also
feature a logic supply pin (VL) that sets the switching points
of the DE and DI inputs to be compatible with a lower supply
voltage in mixed voltage systems.
For companion single RS-485 receivers in micro packages,
please see the ISL3280E, ISL3281E, ISL3282E, ISL3283E,
ISL3284E data sheet.
