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 datasheet.

NAME
FUNCTION
DE Driver output enable. The driver outputs, Y and Z, are enabled by
bringing DE high, and are high impedance when DE is low. If the
driver enable function isn’t needed, connect DE to VCC (or VL)
through a 1kΩ to 3kΩ resistor.
DI Driver input. A low on DI forces output Y low and output Z high.
Similarly, a high on DI forces output Y high and output Z low.
GND Ground connection. This is also the potential of the TDFN
thermal pad.
Y ±15kV HBM, ±7kV IEC61000 (contact method) ESD Protected
RS-485/422 level, noninverting transmitter output.
Z ±15kV HBM, ±7kV IEC61000 (contact method) ESD Protected
RS-485/422 level, inverting transmitter output.
VCC System power supply input (3.0V to 5.5V). On devices with a VL
pin powered from a separate supply, power-up VCC first.
VL Logic-level supply which sets the VIL/VIH levels for the DI and DE
pins (ISL3296E, ISL3297E, ISL3298E only). If VL and VCC are
different supplies, power-up this supply after VCC, and keep
VL VCC.
