DESCRIPTION
The SN65LVDS104 and SN65LVDS105 are a differential line receiver and a LVTTL input (respectively)
connected to four differential line drivers that implement the electrical characteristics of low-voltage
differential signaling (LVDS). LVDS, as specified in
EIA/TIA-644 is a data signaling technique that offers
low-power, low-noise coupling, and switching speeds
to transmit data at relatively long distances. (Note:
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 system characteristics.)

The intended application of this device and signaling technique is for point-to-point baseband data transmission
over controlled impedance media of approximately 100 Ω. The transmission media may be printed-circuit board
traces, backplanes, or cables. Having the drivers integrated into the same substrate, along with the low pulse
skew of balanced signaling, allows extremely precise timing alignment of the signals repeated from the input.
This is particularly advantageous in distribution or expansion of signals such as clock or serial data stream.

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.

APPLICATION INFORMATION (continued)
FAIL SAFE
A common problem 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 –100 mV and 100 mV and within
its recommended input common-mode voltage range. Hovever, TI LVDS receivers handles the open-input circuit
situation differently.
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 33. 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.

VIT ≈ 2.3 V
Figure 33. Open-Circuit Fail Safe of the LVDS Receiver
It is only under these conditions that the output of the receiver will be valid with less than a 100 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 Figure 33. 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.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

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)
