DATASHEET
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.
VLLogic-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
VLVCC.

Application Information
RS-485 and RS-422 are differential (balanced) data
transmission standards for use in long haul or noisy
environments. RS-422 is a subset of RS-485, so RS-485
transmitters and receivers are also RS-422 compliant. RS-422 is
a point-to-multipoint (multidrop) standard, which allows only one
driver and up to 10 (assuming one unit load devices) receivers on
each bus. RS-485 is a true multipoint standard, which allows up
to 32 one unit load devices (any combination of drivers and
receivers) on each bus. To allow for multipoint operation, the
RS-485 specification requires that drivers must handle bus
contention without sustaining any damage.
Another important advantage of RS-485 is the extended
Common-Mode Range (CMR), which specifies that the driver
outputs and receiver inputs withstand signals that range from
+12V to -7V. RS-422 and RS-485 are intended for runs as long as
4000’, so the wide CMR is necessary to handle ground potential
differences, as well as voltages induced in the cable by external
fields.
Driver Features
These RS-485/RS-422 drivers are differential output devices that
delivers at least 1.5V across a 54Ω load (RS-485) and at least 2V
across a 100Ω load (RS-422). The drivers feature low
propagation delay skew to maximize bit width and to minimize
EMI.
All drivers are tri-statable via the active high DE input. If the Tx
enable function is not needed, tie DE to VCC (or VL) through a 1kΩ
to 3kΩ resistor.
The 250kbps and 500kbps driver outputs are slew rate limited to
minimize EMI, and to reduce reflections in unterminated or
improperly terminated networks. Outputs of the ISL3295E and
ISL3298E drivers are not limited, so faster output transition
times allow data rates of at least 20Mbps.
Wide Supply Range
The ISL3293E through ISL3298E are optimized for 3.3V
operation, but can be operated with supply voltages as high as
5.5V. These devices meet the RS-422 and RS-485
specifications for supply voltages less than 4V, and are RS-422
and RS-485 compatible for supplies greater than 4V. Operation
at +125°C requires VCC 3.6V, while 5V operation requires
adding output current limiting resistors (as described in the
Driver Overload Protection” on page 10) if output short-circuits
(e.g., from bus contention) are a possibility.
5.5V Tolerant Logic Pins
Logic input pins (DI, DE) contain no ESD nor parasitic diodes to
VCC (nor to VL), so they withstand input voltages exceeding 5.5V
regardless of the VCC and VL voltages.
Logic Supply (VL Pin, ISL3296E through
ISL3298E)
Note: If powered from separate supplies, power-up VCC before
powering up the VL supply and keep VL VCC.
The ISL3296E through ISL3298E include a VL pin that powers the
logic inputs (DI and DE). These pins interface with “logic” devices
such as UARTs, ASICs, and µcontrollers, and today most of these
devices use power supplies significantly lower than 3.3V. Thus,
the logic device’s low VOH might not exceed the VIH of a 3.3V or
5V powered DI or DE input. Connecting the VL pin to the power
supply of the logic device (as shown in Figure 8) reduces the DI
and DE input switching points to values compatible with the logic
device’s output levels. Tailoring the logic pin input switching
points and output levels to the supply voltage of the UART, ASIC,
or µcontroller eliminates the need for a level shifter/translator
between the two ICs.

VL can be anywhere from VCC down to 1.35V, but the input
switching points may not provide enough noise margin and
20Mbps data rates may not be achievable, when VL<1.5V.
Table 2 indicates typical VIH and VIL values for various VL settings
so the user can ascertain whether or not a particular VL voltage
meets his needs.
The VL supply current (IL) is typically much less than 20µA, as
shown in Figure 12 on page 11, when DE and DI are
above/below VIH/VIL.
Hot Plug Function
When a piece of equipment powers up, there is a period of time
where the processor or ASIC driving the RS-485 control line (DE)
is unable to ensure that the RS-485 Tx outputs are kept disabled.
If the equipment is connected to the bus, a driver activating
prematurely during power-up may crash the bus. To avoid this
scenario, the ISL329xE family incorporates a “Hot Plug” function.
During power-up, circuitry monitoring VCC ensures that the Tx
outputs remain disabled for a period of time, regardless of the state
of DE. This gives the processor/ASIC a chance to stabilize and drive
the RS-485 control lines to the proper states.
ESD Protection
All pins on these devices include class 3 (8kV) Human Body
Model (HBM) ESD protection structures, but the RS-485 pins
(driver outputs) incorporate advanced structures allowing them
to survive ESD events in excess of ±16.5kV HBM and ±7kV to
the IEC61000 contact test method. The RS-485 pins are
particularly vulnerable to ESD damage because they typically
connect to an exposed port on the exterior of the finished
product. Simply touching the port pins, or connecting a cable,
can cause an ESD event that might destroy unprotected ICs.
These new ESD structures protect the device whether or not it is
powered up and without degrading the RS-485 common-mode
range of -7V to +12V. This built-in ESD protection eliminates the
need for board level protection structures (e.g., transient
suppression diodes) and the associated, undesirable capacitive
load they present.
Data Rate, Cables and Terminations
RS-485/RS-422 are intended for network lengths up to 4000’,
but the maximum system data rate decreases as the
transmission length increases. Devices operating at 20Mbps are
limited to lengths less than 100’, while the 250kbps versions can
operate at full data rates with lengths of several 1000’.
Twisted pair is the cable of choice for RS-485/RS-422 networks.
Twisted pair cables tend to pick up noise and other
electromagnetically induced voltages as common-mode signals,
which are effectively rejected by the differential receivers in
these ICs.
Proper termination is imperative, when using the 20Mbps
devices, to minimize reflections. Short networks using the
250kbps versions need not be terminated, but, terminations are
recommended unless power dissipation is an overriding concern.
In point-to-point, or point-to-multipoint (single driver on bus)
networks, the main cable should be terminated in its
characteristic impedance (typically 120Ω) at the end farthest
from the driver. In multireceiver applications, stubs connecting
receivers to the main cable should be kept as short as possible.
Multipoint (multidriver) systems require that the main cable be
terminated in its characteristic impedance at both ends. Stubs
connecting a transmitter or receiver to the main cable should be
kept as short as possible.
Driver Overload Protection
As stated previously, the RS-485 specification requires that
drivers survive worst case bus contentions undamaged. These
drivers meet this requirement, for VCC 3.6V, via driver output
short-circuit current limits and on-chip thermal shutdown
circuitry.
The driver output stages incorporate short-circuit current limiting
circuitry, which ensures that the output current never exceeds the
RS-485 specification, for VCC 3.6V, even at the common-mode
voltage range extremes. Additionally, these devices utilize a
foldback circuit which reduces the short-circuit current and thus
the power dissipation, whenever the contending voltage exceeds
either VCC or GND.

In the event of a major short-circuit condition, devices also include
a thermal shutdown feature that disables the drivers whenever the
die temperature becomes excessive. This eliminates the power
dissipation, allowing the die to cool. The drivers automatically
reenable after the die temperature drops about +20°C. If the
contention persists, the thermal shutdown/reenable cycle repeats
until the fault is cleared.
At VCC > 3.6V, the instantaneous short-circuit current is high
enough that output stage damage may occur during short-circuit
conditions to voltages outside of GND to VCC, before the
short-circuit limiting and thermal shutdown activate. For
VCC = 5V operation, if output short-circuits are a possibility
(e.g., due to bus contention), it is recommended that a 5Ω
resistor be inserted in series with each output. This resistor limits
the instantaneous current below levels that can cause damage.
The driver VOD at VCC = 5V is so large that this small added
resistance has little impact.
High Temperature Operation
Due to power dissipation and instantaneous output short-circuit
current levels at VCC = 5V, these transmitters may not be
operated at +125°C with VCC > 3.6V.
At VCC = 3.6V, even the SOT-23 versions may be operated at
+125°C, while driving a 100’, double terminated, CAT 5 cable at
20Mbps, without triggering the thermal SHDN circuit.
Low Power Shutdown Mode
These BiCMOS transmitters all use a fraction of the power
required by their bipolar counterparts, but they also include a
shutdown feature that reduces the already low quiescent ICC to a
1µA trickle. These devices enter shutdown whenever the driver
disables (DE = GND).
