Data Sheet
GENERAL DESCRIPTION
The ADM3065E is a 3.0 V to 5.5 V, IEC electrostatic discharge
(ESD) protected RS-485 transceiver, allowing the device to
withstand 12 kV contact discharges on the transceiver bus
pins without latch-up or damage. The ADM3066E/ADM3062E
features a VIO logic supply pin allowing a flexible digital interface
capable of operating as low as 1.62 V.
The RS-485 transceivers are available in a number of space-
saving packages, such as a 10-lead, 3 mm × 3 mm LFCSP, an 8-lead,
3 mm × 3 mm MSOP, a 10-lead, 3 mm × 3 mm MSOP, and an 8-
lead, narrow body SOIC package. Models with operating
temperature ranges of −40°C to +125°C and −40°C to +85°C
are available.
The ADM3065E/ADM3066E are suitable for high speed,
50 Mbps, bidirectional data communication on multipoint bus
transmission lines. The
ADM3061E/ADM3062E/ADM3065E/ADM3066E feature a ¼
unit load input impedance, which allows up to 128 transceivers
on a bus. The ADM3061E/ADM3062E models offer all of the
same features as the ADM3065E/ADM3066E models, but at a
low 500 kbps data rate suitable for operation over long cable
runs.
Excessive power dissipation caused by bus contention or by
output shorting is prevented by a thermal shutdown circuit. If,
during fault conditions, a significant temperature increase is
detected in the internal driver circuitry, this feature forces the
driver output into a high impedance state.
The ADM3061E/ADM3062E/ADM3065E/ADM3066E
guarantee a logic high receiver output when the receiver inputs
are shorted, open, or connected to a terminated transmission
line with all drivers disabled.
The ADM3061E/ADM3062E/ADM3065E/ADM3066E are half-
duplex RS-485 transceivers, fully compliant to the Profibus®
Table 1 presents an overview of the ADM3061E/ADM3062E/
ADM3065E/ADM3066E data rate capability across temperature,
power supply, and package options. Refer to the Ordering Guide
for model numbering.

12 ꢀV contact discharge on transceiver bus pins (A and B)
without latch-up or damage. The ADM3061E/ADM3062E has

Figure 41. IEC 61000-4-2 ESD Waveform (8 kV)
Figure 42 shows the 8 ꢀV contact discharge current waveform
from the IEC 61000-4-2 standard compared to the HBM ESD
8 ꢀV waveform. Figure 42 shows that the two standards specify a
different waveform shape and peaꢀ current. The peaꢀ current
associated with an IEC 61000-4-2 8 ꢀV pulse is 30 A, whereas
the corresponding peaꢀ current for HBM ESD is more than five
times less, at 5.33 A. The other difference is the rise time of the
initial voltage spiꢀe, with the IEC 61000-4-2 ESD waveform having
a much faster rise time of 1 ns, compared to the 10 ns associated
with the HBM ESD waveform. The amount of power associated
with an IEC ESD waveform is much greater than that of an
HBM ESD waveform. The HBM ESD standard requires the
EUT to be subjected to three positive and three negative
discharges, while in comparison, the IEC ESD standard requires
10 positive and 10 negative discharge tests.
IEC 61000-4-2 ESD PROTECTION
ESD is the sudden transfer of electrostatic charge between
bodies at different potentials caused by near contact or induced
by an electric field. It has the characteristics of high current in a
short time period. The primary purpose of the IEC 61000-4-2
test is to determine the immunity of systems to external ESD
events outside the system during operation. IEC 61000-4-2
describes testing using two coupling methods: contact discharge
and air discharge. Contact discharge implies a direct contact
between the discharge gun and the equipment under test (EUT).
During air discharge testing, the charged electrode of the
discharge gun is moved toward the EUT until a discharge
occurs as an arc across the air gap. The discharge gun does not
maꢀe direct contact with the EUT. A number of factors affect
the results and repeatability of the air discharge test, including
humidity, temperature, barometric pressure, distance, and rate
of approach to the EUT. This method is a better representation
of an actual ESD event but is not as repeatable. Therefore,
contact discharge is the preferred test method.
The ADM3061E/ADM3062E/ADM3065E/ADM3066E with IEC
61000-4-2 ESD ratings is better suited for operation in harsh
environments compared to other RS-485 transceivers that state
varying levels of HBM ESD protection.

PEAK
During testing, the data port is subjected to at least 10 positive

dependent on the system end environment.

RECEIVER FAIL-SAFE
The ADM3061E/ADM3062E/ADM3065E/ADM3066E guarantee
a logic high receiver output when the receiver inputs are
shorted, open, or connected to a terminated transmission line
with all drivers disabled; set the receiver input threshold
between −30 mV and −200 mV. If the differential receiver input
voltage (A − B) is greater than or equal to −30 m V, the RO pin
is logic high.

If the A − B input is less than or equal to −200 mV, RO is logic
low. In the case of a terminated bus with all transmitters
disabled, the receiver differential input voltage is pulled to 0 V
by the termination, resulting in a logic high with a 30 mV
minimum noise margin.

HOT SWAP CAPABILITY
DRIVER OUTPUT PROTECTION
Hot Swap Inputs
The ADM3061E/ADM3062E/ADM3065E/ADM3066E features
two methods to prevent excessive output current and power
dissipation caused by faults or by bus contention. Current-limit
protection on the output stage provides immediate protection
against short circuits over the whole common-mode voltage range.
In addition, a thermal shutdown circuit forces the driver outputs
into a high impedance state if the die temperature rises excessively.
This circuitry is designed to disable the driver outputs when a die
temperature of 150°C is reached. As the device cools, the drivers are
reenabled at a temperature of 140°C.
When a circuit board is inserted into a powered (or hot)
backplane, differential disturbances to the data bus can lead to
data errors. During this period, processor logic output drivers
RE
are high impedance and are unable to drive the DE and
inputs
of the RS-485 transceivers to a defined logic level. Leakage currents
up to 10 µA from the high impedance state of the processor logic
drivers can cause standard CMOS enable inputs of a transceiver to
drift to an incorrect logic level. Additionally, parasitic circuit board
capacitance can cause coupling of VCC or GND to the enable inputs.
Without the hot swap capability, these factors can improperly
enable the driver or receiver of the transceiver. When VCC or VIO
RE
rises, an internal pull-down circuit holds DE low and
high.
After the initial power-up sequence, the pull-down circuit
becomes transparent resetting the hot swap tolerable input.
128 TRANSCEIVERS ON THE BUS
The standard RS-485 receiver input impedance is 12 kΩ
(1 unit load), and the standard driver can drive up to 32 unit
loads. The ADM3061E/ADM3062E/ADM3065E/ADM3066E
transceivers have a ¼ unit load receiver input impedance (48
kΩ), allowing up to 128 transceivers to be connected in parallel
on one communication line. Any combination of these devices
and other RS-485 transceivers with a total of 32 unit loads or
fewer can be connected to the line.

APPLICATIONS INFORMATION
The ADM3061E/ADM3065E transceiver is designed for
bidirectional data communications on multipoint bus transmission
lines. Figure 43 shows a typical network applications circuit.
To minimize reflections, terminate the line at both ends with a
termination resistor (the value of the termination resistor must
be equal to the characteristic impedance of the cable used) and
keep stub lengths off the main line as short as possible.

If 5 V operation is desired, VSEL on ADuM6000 can be tied to
ISOLATED HIGH SPEED RS-485 NODE
VISO, and the maximum supported data rate becomes lower (for
Galvanic isolation, with reinforced insulation and 5 kV rms
transient withstand voltage, can be added to the ADM3065E using
Analog Devices, Inc., iCoupler® and isoPower® technology. The
ADuM6401 provides the required quad channels of 5 kV rms
signal isolation, operating at rates up to 25 Mbps, together with
an integrated dc-to-dc converter. The ADuM6401 combines
with the ADM3065E (shown in Figure 44) with the VISO pin
configured for 3.3 V by connecting the VSEL pin to GNDISO and
a 5 V supply connected to VDD1. Operation at 3.3 V ensures the
ADM3065E remains within the load capability of ADuM6401
even at 25 Mbps.
example, <10 Mbps). Refer to the Typical Performance
Characteristics section, ADuM241D data sheet, and the
ADuM6000 data sheet.
The dc-to-dc converters in the ADuM6401 and ADuM6000
isoPower devices provide regulated, isolated power to the
ADM3065E (and the ADuM241D). These isoPower devices use
high frequency switching elements to transfer power through
their transformers. Take care during PCB layout to meet
emissions standards. See the AN-0971 Application Note for
PCB layout recommendations.
Operation at 50 Mbps data rates with isolation of the ADM3065E
can be implemented using the ADuM241D quad-channel digital
isolator and the ADuM6000 isolated dc-to-dc converter, as shown
in Figure 45. The ADuM241D can operate at a data rate of up to
150 Mbps, offering the precise timing required to fully support the
ADM3065E at 50 Mbps. Operation of ADM3065E at 3.3 V allows
operation at the 50 Mbps data rate.
