SN65HVD2x Extended Common-Mode RS-485 Transceivers
1 Features
3 Description
•
The transceivers in the SN65HVD2x family offer
performance far exceeding typical RS-485 devices.
In addition to meeting all requirements of the
TIA/EIA‑485-A standard. The SN65HVD2x family
operates over an extended range of common-mode
voltages and has features such as high ESD
protection, wide receiver hysteresis, and failsafe
operation. This family of devices is designed for longcable networks, and other applications where the
environment is too harsh for ordinary transceivers.
•
•
•
•
•
•
Common-mode voltage range (–20 V to 25 V)
more than doubles TIA/EIA-485 requirement
Receiver equalization extends cable length,
signaling rate (SN65HVD2[3,4])
Reduced unit-load for up to 256 nodes
Bus I/O protection to over 16-kV HBM
Failsafe receiver for open-circuit, short-circuit, and
idle-bus conditions
Low standby supply current 1 µA (maximum)
More than 100 mV receiver hysteresis
2 Applications
•
Long cable solutions
– Factory automation
– Security networks
– Building HVAC
Severe electrical environments
– Electrical power inverters
– Industrial drives
– Avionics
These devices combine a 3-state differential driver
and a differential receiver that operate from a single
5-V power supply. The driver differential outputs and
the receiver differential inputs are connected internally
to form a differential bus port that offers minimum
loading to the bus. This port features an extended
common-mode voltage range, making the device
suitable for multipoint applications over long cable
runs.

5 Description (continued)
The SN65HVD20 device provides high signaling rate (up to 25 Mbps) for interconnecting networks of up to 64
nodes.
The SN65HVD21 device allows up to 256 connected nodes at moderate data rates (up to 5 Mbps). The driver
output slew rate is controlled to provide reliable switching with shaped transitions which reduce high-frequency
noise emissions.
The SN65HVD22 device has controlled driver output slew rate for low radiated noise in emission-sensitive
applications and for improved signal quality with long stubs. Up to 256 SN65HVD22 nodes can be connected at
signaling rates up to 500 kbps.
The SN65HVD23 device implements receiver equalization technology for improved jitter performance on
differential bus applications with data rates up to 25 Mbps at cable lengths up to 160 meters.
The SN65HVD24 device implements receiver equalization technology for improved jitter performance on
differential bus applications with data rates from 1 Mbps to 10 Mbps at cable lengths up to 1000 meters.
The receivers include a failsafe circuit that provides a high-level output within 250 microseconds after loss of the
input signal. The most common causes of signal loss are disconnected cables, shorted lines, or the absence of
any active transmitters on the bus. This feature prevents noise from being received as valid data under these
fault conditions. This feature may be used for Wired-OR bus signaling.
The SN65HVD2x devices are characterized for operation temperatures from –40°C to 85°C.

10 Detailed Description
10.1 Overview
The SN65HVD2x family of devices are RS-485 compliant half-duplex transceivers designed for communication
rates up to 500 kbps (SN65HVD22), 3 Mbps (SN65HVD24), 5 Mbps (SN65HVD21), or 25 Mpbs (SN65HVD20
and SN65HVD23). The devices feature extended common-mode range support, which provides immunity to
larger ground potential differences that can occur between nodes that communicate over longer distances.
The SN65HVD23 and the SN65HVD24 devices feature receiver equalization, which reduces the amount of
data-dependent jitter that is introduced by the high-frequency losses associated with long cables.

10.3 Feature Description
The SN65HVD2x family of devices integrates a differential receiver and differential driver with additional features
for improved performance in electrically-noisy, long-cable, or other fault-intolerant applications.
The receiver hysteresis (typically 130 mV) is much larger than found in typical RS-485 transceivers. This helps
reject spurious noise signals which would otherwise cause false changes in the receiver output state.
Slew rate limiting on the driver outputs (SN65HVD2[1,2,4]) reduces the high-frequency content of signal edges.
This decreases reflections from bus discontinuities, and allows longer stub lengths between nodes and the
main bus line. Designers must consider the maximum signaling rate and cable length required for a specific
application, and choose the transceiver best matching those requirements.
When DE is low, the differential driver is disabled, and the A and B outputs are in high-impedance states. When
DE is high, the differential driver is enabled, and drives the A and B outputs according to the state of the D
inputs.
When RE is high, the differential receiver output buffer is disabled, and the R output is in a high-impedance
state. When RE is low, the differential receiver is enabled, and the R output reflects the state of the differential
bus inputs on the A and B pins.

SLLS552G – DECEMBER 2002 – REVISED SEPTEMBER 2022
If both the driver and receiver are disabled, (DE low and RE high) then all nonessential circuitry, including
auxiliary functions such as failsafe and receiver equalization is placed in a low-power standby state. This
reduces power consumption to less than 5 µW. When either enable input is asserted, the circuitry again
becomes active.
In addition to the primary differential receiver, these devices incorporate a set of comparators and logic to
implement an active receiver failsafe feature. These components determine whether the differential bus signal
is valid. Whenever the differential signal is close to zero volts (neither high nor low), a timer initiates, If the
differential input remains within the transition range for more than 250 µs, the timer expires and set the receiver
output to the high state. If a valid bus input (high or low) is received at any time, the receiver output reflects the
valid bus state, and the timer is reset.

10.4.1 Test Mode Driver Disable
If the input signal to the D pin is such that:
1. the signal has signaling rate above 4 Mbps (for the SN65HVD21 and SN65HVD24),
2. the signal has signaling rate above 6 Mbps (for the SN65HVD20 and SN65HVD23),
3. the signal has average amplitude from 1.2 V to 1.6 V (1.4 V ± 200 mV), or
4. the average signal amplitude remains in this range for 100 µs or longer,
then the driver may activate a test-mode during which the driver outputs are temporarily disabled. This can
cause loss of transmission of data during the period that the device is in the test-mode. The driver is re-enabled
and resumes normal operation whenever the above conditions are not true. The device is not damaged by this
test mode.
Although rare, there are combinations of specific voltage levels and input data patterns within the operating
conditions of the SN65HVD2x family which may lead to a temporary state where the driver outputs are disabled
for a period of time.
Observations:
1. The conditions for inadvertently entering the test mode are dependent on the levels, duration, and duty cycle
of the logic signal input to the D pin. Operating input levels are specified as greater than 2 V for a logic HIGH
input, and less than 0.8 V for a logic LOW input. Therefore, a valid steady-state logic input does not cause
the device to activate the test mode
2. Only input signals with frequency content above 2 MHz (4 Mbps) have a possibility of activating the test
mode. Therefore, this issue should not affect the normal operation of the SN65HVD22 (500 kbps).
3. For operating signaling rates of 4 Mbps (or above), the conditions stated above must remain true over a
period of: 4 Mbps ×100 µs = 400 bits. Therefore, a normal short message does not inadvertently activate the
test model.
4. One example of an input signal which may cause the test mode to activate is a clock signal with frequency
3 MHz and 50% duty cycle (symmetric HIGH and LOW half-cycles) with logic HIGH levels of 2.4 V and logic
LOW levels of 0.4 V. This signal applied to the D pin as a driver input would meet the criteria listed above,
and may cause the test-mode to activate, which would disable the driver. This example situation may occur if
the clock signal is generated from a microcontroller or logic chip with a 2.7-V supply.

11 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.
11.1 Application Information
The SN65HVD2x devices are half-duplex RS-485 transceivers that can be used for bidirectional, multipoint
communication at various data rates over differential transmission lines. These devices support a wide commonmode range, allowing for robust communication even in the presence of voltage differences between the
reference potentials of different nodes on a network.
11.2 Typical Application
Figure 11-1 shows a typical RS-485 application. Transceivers of different nodes are connected to one another
over a shared bus. Twisted-pair cabling with a controlled differential impedance is used, and termination
resistances are placed at the two ends of the cable to match the transmission line impedance and minimize
signal reflections.

11.2.1 Design Requirements
As the distances between nodes in an RS-485 network become greater and greater, it becomes more of a
challenge to ensure reliable communication. The increased distance often means that the reference (ground)
potentials has more of a difference between nodes. These ground potential differences give rise to differences
in the common-mode voltages seen by the various transceivers on the bus. Standard RS-485 transceivers are
typically specified to operate over a common-mode voltage from –7 V to 12 V, which may be insufficient for
larger distances. The SN65HVD2x family of devices extends this range to –20 V to 25 V, allowing for greater
communication distances between nodes.
Increased cable lengths can lead to increased jitter, especially in links operating at high data rates. This
increased jitter is due to the attenuation of the cable, which tends to increase with frequency. Having unequal
loss between higher and lower frequencies causes the RS-485 signal to distort, adding some timing deviation
(jitter) to the edge crossings of the RS-485 data. If the jitter amplitude exceeds the jitter tolerance of the receiving
MCU or UART, then bit errors are likely to result in the link. However, jitter can be reduced for a given link
through the use of receiver equalization.
11.2.2 Detailed Design Procedure
11.2.2.1 Noise Considerations for Equalized Receivers
The simplest way of overcoming the effects of cable losses is to increase the sensitivity of the receiver. If
the maximum attenuation of frequencies of interest is 20 dB, increasing the receiver gain by a factor of ten
compensates for the cable. However, this means that signal and noise are amplified. Therefore, the receiver with

higher gain is more sensitive to noise and it is important to minimize differential noise coupling to the equalized
receiver.
Differential noise is crated when conducted or radiated noise energy generates more voltage on one line of
the differential pair than the other. For this to occur from conducted or electric far-field noise, the impedance to
ground of the lines must differ.
For noise frequency out to 50 MHz, the input traces can be treated as a lumped capacitance if the receiver is
approximately 10 inches or less from the connector. Therefore, matching impedance of the lines is accomplished
by matching the lumped capacitance of each.
The primary factors that affect the capacitance of a trace are in length, thickness, width, dielectric material,
distance from the signal return path, stray capacitance, and proximity to other conductors. It is difficult to match
each of the variables for each line of the differential pair exactly, but a reasonable effort to do so keeps the lines
balanced and less susceptible to differential noise coupling.
Another source of differential noise is from near-field coupling. In this situation, an assumption of equal noisesource impedance cannot be made as in the far-field. Familiarly known as crosstalk, more energy from a nearby
signal is coupled to one line of the differential pair. Minimization of this differential noise is accomplished by
keeping the signal pair close together and physical separation from high-voltage, high-current, or high-frequency
signals.
In summary, follow these guidelines in board layout for keeping differential noise to a minimum.
•
•
•
•
•
Keep the differential input traces short.
Match the length, physical dimensions, and routing of each line of the pair.
Keep the lines close together.
Match components connected to each line.
Separate the inputs from high-voltage, high-frequency, or high-current signals.
11.2.3 Application Curves
Figure 11-2 illustrates the benefits of integrated receiver equalization as implemented in the SN65HVD23
transceiver. In this test setup, a differential signal generator applied a signal voltage at one end of the cable,
which was Belden 3105A twisted-pair shielded cable. The test signal was a pseudo-random bit stream (PRBS)
of nonreturn-to-zero (NRZ) data. Channel 1 (top) shows the eye-pattern of the differential voltage at the receiver
inputs (after the cable attenuation). Channel 2 (bottom) shows the output of the receiver.
Figure 11-3 illustrates the benefits of integrated receiver equalization as implemented in the SN65HVD24
transceiver. In this test setup, a differential signal generator applied a signal voltage at one end of the cable,
which was Belden 3105A twisted-pair shielded cable. The test signal was a pseudo-random bit stream (PRBS)
of nonreturn-to-zero (NRZ) data. Channel 1 (top) shows the eye-pattern of the bit stream. Channel 2 (middle)
shows the eye-pattern of the differential voltage at the receiver inputs (after the cable attenuation). Channel 3
(bottom) shows the output of the receiver.

12 Power Supply Recommendations
To ensure reliable operation at all data rates and supply voltages, each supply must be decoupled with a 100-nF
ceramic capacitor placed as close to the supply pins as possible. This helps to reduce supply voltage ripple
present on the outputs of switched-mode power supplies and also helps to compensate for the resistance and
inductance of the PCB power planes.

13 Layout
13.1 Layout Guidelines
In addition to the guidelines on differential trace matching given in Section 11.2.2, the layout guidelines below
must be followed:
•
•
•
Route power and ground nets as planes rather than traces, and keep their widths as large as possible to
minimize resistance and inductance while maximizing parasitic capacitance.
If external components (like transient voltage suppression diodes) are used for transient protection, place
them close to the connector port and within the path of the signal lines. Make sure component capacitances
are small enough not to impact the RS-485 signaling at the chosen data rate.
Small-valued series pulse-proof resistances can be used to provide additional immunity to transients. This
is needed to limit input currents if the clamping voltages of external transient protection devices exceed the
absolute maximum ratings of the transceiver. These resistances must be less than 10 Ω so that the RS-485
signal is not overly attenuated.
