June 22, 2007
±15kV ESD Protected, 3.3V, Full Fail-safe,
Low Power, High Speed or Slew Rate
Limited, RS-485/RS-422 Transceivers
The Intersil ISL8307XE are BiCMOS 3.3V powered, single
transceivers that meet both the RS-485 and RS-422
standards for balanced communication. These devices have
very low bus currents (+125mA/-100mA), so they present a
true “1/8 unit load” to the RS-485 bus. This allows up to 256
transceivers on the network without violating the RS-485
specification’s 32 unit load maximum, and without using
repeaters. For example, in a remote utility meter reading
system, individual meter readings are routed to a
concentrator via an RS-485 network, so the high allowed
node count minimizes the number of repeaters required.
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which
ensures a logic high Rx output if Rx inputs are floating,
shorted, or terminated but undriven.

Hot Plug circuitry ensures that the Tx and Rx outputs remain
in a high impedance state while the power supply stabilizes.
• Half and Full Duplex Pinouts
The ISL83070E through ISL83075E utilize slew rate limited
drivers which reduce EMI, and minimize reflections from
improperly terminated transmission lines, or unterminated
stubs in multidrop and multipoint applications. Slew rate limited
versions also include receiver input filtering to enhance noise
immunity in the presence of slow input signals.
• Current Limiting and Thermal Shutdown for driver
Overload Protection
The ISL83070E, ISL83071E, ISL83073E, ISL83076E,
ISL83077E are configured for full duplex (separate Rx input
and Tx output pins) applications. The half duplex versions
multiplex the Rx inputs and Tx outputs to allow transceivers
with output disable functions in 8 lead packages.
• Three State Rx and Tx Outputs Available

FUNCTION
RO
Receiver output: If A - B ≥ -50mV, RO is high; If A - B ≤ -200mV, RO is low; RO = High if A and B are unconnected (floating) or shorted.
RE
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. If the Rx enable function isn’t
required, connect RE directly to GND or through a 1kΩ to 3kΩ resistor to GND.
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
Tx enable function isn’t required, connect DE to VCC 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.
A/Y
±15kV HBM ESD Protected RS-485/RS-422 level, noninverting receiver input and noninverting driver output. Pin is an input if DE =

NOTES:
4. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise
specified.
5. Supply current specification is valid for loaded drivers when DE = 0V.
6. Applies to peak current. See “Typical Performance Curves” for more information.
7. When testing devices with the shutdown feature, keep RE = 0 to prevent the device from entering SHDN.
8. When testing devices with the shutdown feature, the RE signal high time must be short enough (typically <100ns) to prevent the device from
entering SHDN.
9. Versions with a shutdown feature are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts
are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See
“Low Power Shutdown Mode” on page 11.
10. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.
11. Set the RE signal high time >600ns to ensure that the device enters SHDN.
12. Does not apply to the ISL83071E and ISL83077E.
13. ΔtSKEW is the magnitude of the difference in propagation delays of the specified terminals of two units tested with identical test conditions (VCC,
temperature, etc.). Only applies to the ISL83076E - 78E.
14. ISL83070E - ISL83075E only.
15. VCC ≥ 3.15V
16. Limits established by characterization and are not production tested.
17. If the Tx or Rx enable function isn’t needed, connect the enable pin to the appropriate supply (see “Pin Descriptions” table) through a 1kΩ to 3kΩ
resistor.
18. Parts are 100% tested at +25°C. Full temperature limits are guaranteed by bench and tester characterization.

Application Information
Receiver Features
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
transceivers are also RS-422 compliant. RS-422 is a pointto-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 spec requires that
drivers must handle bus contention without sustaining any
damage.
These devices utilize a differential input receiver for maximum
noise immunity and common mode rejection. Input sensitivity
is better than ±200mV, as required by the RS-422 and RS-485
specifications.
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.
10
Receiver input resistance of 96kΩ surpasses the RS-422
spec of 4kΩ, and is eight times the RS-485 “Unit Load (UL)”
requirement of 12kΩ minimum. Thus, these products are
known as “one-eighth UL” transceivers, and there can be up
to 256 of these devices on a network while still complying
with the RS-485 loading spec.
Receiver inputs function with common mode voltages as great
as +9V/-7V outside the power supplies (i.e., +12V and -7V),
making them ideal for long networks where induced voltages,
and ground potential differences, are realistic concerns.
All the receivers include a “full fail-safe” function that
guarantees a high level receiver output if the receiver inputs
are unconnected (floating) or shorted. Fail-safe with shorted
inputs is achieved by setting the Rx upper switching point to
-50mV, thereby ensuring that the Rx sees 0V differential as a
high input level.

ISL83070E, ISL83071E, ISL83072E, ISL83073E, ISL83075E, ISL83076E, ISL83077E, ISL83078E
Receivers easily meet the data rates supported by the
corresponding driver, and all receiver outputs (except on the
ISL83071E and ISL83077E) are tri-statable via the active
low RE input.
Driver Features
The RS-485, RS-422 driver is a differential output device
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, except
on the ISL83071E and ISL83077E.
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 ISL83076E through ISL83078E drivers are not limited,
so faster output transition times allow data rates of at least
20Mbps.
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
lines (DE, RE) is unable to ensure that the RS-485 Tx and
Rx 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 ISL8307XE
versions with output enable pins incorporate a “Hot Plug”
function. During power up, circuitry monitoring VCC ensures
that the Tx and Rx outputs remain disabled for a period of time,
regardless of the state of DE and RE. 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 (>7kV) Human
Body Model (HBM) ESD protection structures, but the
RS-485 pins (driver outputs and receiver inputs)
incorporate advanced structures allowing them to survive
ESD events in excess of ±15kV HBM. 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, protect
without allowing any latchup mechanism to activate, 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
11
versions can operate at full data rates with lengths of several
thousand feet.
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 multi-receiver applications, stubs
connecting receivers to the main cable should be kept as
short as possible. Multipoint (multi-driver) systems require
that the main cable be terminated in its characteristic
impedance at both ends. Stubs connecting a transceiver to
the main cable should be kept as short as possible.
Built-In Driver Overload Protection
As stated previously, the RS-485 spec requires that drivers
survive worst case bus contentions undamaged. These
devices meet this requirement 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 spec, 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 supply.
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 re-enable after the die temperature
drops about +15°. If the contention persists, the thermal
shutdown/re-enable cycle repeats until the fault is cleared.
Receivers stay operational during thermal shutdown.
Low Power Shutdown Mode
These CMOS transceivers all use a fraction of the power
required by their bipolar counterparts, but some also include a
shutdown feature that reduces the already low quiescent ICC to
a 10nA trickle. These devices enter shutdown whenever the
receiver and driver are simultaneously disabled (RE = VCC
and DE = GND) for a period of at least 600ns. Disabling both
the driver and the receiver for less than 50ns guarantees that
the transceiver will not enter shutdown.
Note that receiver and driver enable times increase when the
transceiver enables from shutdown. Refer to Notes 7 through
11, at the end of the “Electrical Specifications” table on page 8
for more information.
