DESCRIPTION
The
SN65LVDM179,
SN65LVDM180,
SN65LVDM050, and SN65LVDM051 are differential
line drivers and receivers that use low-voltage
differential signaling (LVDS) to achieve high
signaling rates. These circuits are similar to
TIA/EIA-644
standard
compliant
devices
(SN65LVDS) counterparts, except that the output
current of the drivers is doubled. This modification
provides a minimum differential output voltage
magnitude of 247 mV across a 50-Ω load simulating
two transmission lines in parallel. This allows having
data buses with more than one driver or with two line
termination resistors. The receivers detect a voltage
difference of 50 mV with up to 1 V of ground
potential difference between a transmitter and
receiver.
The intended application of these devices and
signaling techniques is point-to-point half duplex,
baseband data transmission over a controlled
impedance media of approximately 100 Ω
characteristic impedance.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION (CONTINUED)
The transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate and
distance of data transfer is dependent upon the attenuation characteristics of the media, the noise coupling to
the environment, and other application-specific characteristics.
The SN65LVDM179, SN65LVDM180, SN65LVDM050, and SN65LVDM051 are characterized for operation from
–40°C to 85°C.

APPLICATION INFORMATION (continued)
The devices are generally used as building blocks for high-speed point-to-point data transmission. Ground
differences are less than 1 V with a low common-mode output and balanced interface for very low noise
emissions. Devices can interoperate with RS-422, PECL, and IEEE-P1596. Drivers/receivers maintain ECL
speeds without the power and dual supply requirements.

FAIL SAFE
One of the most common problems with differential signaling applications is how the system responds when no
differential voltage is present on the signal pair. The LVDS receiver is like most differential line receivers, in that
its output logic state can be indeterminate when the differential input voltage is between –50 mV and 50 mV and
within its recommended input common-mode voltage range. TI's LVDS receiver is different, however, in how it
handles the open-input circuit situation.
Open-circuit means that there is little or no input current to the receiver from the data line itself. This could be
when the driver is in a high-impedance state or the cable is disconnected. When this occurs, the LVDS receiver
pulls each line of the signal pair to near VCC through 300-kΩ resistors as shown in Figure 22. The fail-safe
feature uses an AND gate with input voltage thresholds at about 2.3 V to detect this condition and force the
output to a high-level, regardless of the differential input voltage.

Figure 22. Open-Circuit Fail Safe of the LVDS Receiver
It is only under these conditions that the output of the receiver is valid with less than a 50-mV differential input
voltage magnitude. The presence of the termination resistor, Rt, does not affect the fail-safe function as long as
it is connected as shown in the figure. Other termination circuits may allow a dc current to ground that could
defeat the pullup currents from the receiver and the fail-safe feature.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

practice. TI is not responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would
reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement
specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications
of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related
requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any
applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its
representatives against any damages arising out of the use of TI products in such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is
solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in
connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products
are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any
non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
