3 Description
The DS26LV31T is a high-speed quad differential
CMOS driver that meets the requirements of both TIA/
EIA-422-B and ITU-T V.11. The CMOS DS26LV31T
features low static ICC of 100 μA MAX which makes it
ideal for battery powered and power conscious
applications.
Differential outputs have the same VOD specifies (≥2
V) as the 5 V version.
The EN and EN* inputs allow active Low or active
High control of the TRI-STATE outputs. The enables
are common to all four drivers. Protection diodes
protect all the driver inputs against electrostatic
discharge. Outputs have enhanced ESD protection
providing greater than 7 kV tolerance. The driver and
enable inputs (DI, EN, EN*) are compatible with low
voltage LVTTL and LVCMOS devices.

8 Detailed Description
8.1 Overview
The DS26LV31T is a high speed CMOS quadruple differential line drivers with 3-state outputs. The devices are
designed to be similar to TIA/EIA-422-B and ITU Recommendation V.11 drivers with a single 3.3-V power supply.
The drivers also integrate active-high and active-low enables for precise device control.

8.3 Feature Description
The devices can be configured using the EN and EN* logic inputs to select transmitter output. A logic high on the
EN pin or a logic low on the EN* pin enables the device to operate. These pins are simply a way to configure the
logic to match that of the receiving or transmitting controller or microprocessor.
The DS26LV31T are optimized for balanced-bus transmission at switching rates up to 32 MHz.
The CMOS DS26LV31T consumes low static ICC of 100 uA MAX that makes it ideal for battery powered
applications.

9 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. Customers should validate and test their design
implementation to confirm system functionality.
9.1 Application Information
When designing a system that uses drivers, receivers, and transceivers, proper cable termination is essential for
highly reliable applications with reduced reflections in the transmission line. If termination is used, it can be
placed at the end of the cable near the last receiver. A single driver and receiver, TI DS26LV31T and
DS26LV32AT, respectively, were tested at room temperature with a 3.3-V supply voltage. For laboratory
experiments, 100 feet of 120-Ω, 24-AWG, twisted-pair cable (Bertek) was used. The communication was
succssful with 1Mbps data rate.

9.2.2 Design Requirements
Resistor and capacitor (if used) termination values are shown for each laboratory experiment, but vary from
system to system. For example, the termination resistor, RT, must be within 20% of the characteristic
impedance, Zo, of the cable and can vary from about 80 Ω to 120 Ω.
This example requires the following:
3.3-V power source
RS-485 bus operating at 32 MHz or less
Connector that ensures the correct polarity for port pins
9.2.3 Detailed Design Procedure
Ensure values in Absolute Maximum Ratings are not exceeded. Supply voltage, VIH, and VIL must comply with
Recommended Operating Conditions. Place the device close to bus connector to keep traces (stub) short to

prevent adding reflections to the bus line. If desired, add external fail-safe biasing to ensure 200 mV on the A-B
port, if the drive is in high impedance state.

Bypass caps must be used on power pins. High frequency ceramic (surface mount is recommended) 0.1 μF in
parallel with 0.01 μF at the power supply pin. A 10 μF or greater solid tantalum or electrolytic should be
connected at the power entry point on the printed circuit board.

11 Layout
11.1 Layout Guidelines
For best operational performance of the device, use good PCB layout practices, including:
Noise can propagate into analog circuitry through the power pins of the circuit as a whole, as well as the
operational amplifier. Bypass capacitors are used to reduce the coupled noise by providing low impedance
power sources local to the analog circuitry. Connect low-ESR, 0.1-μF ceramic bypass capacitors between
supply pin and ground, placed as close to the device as possible.
Separate grounding for analog and digital portions of circuitry is one of the simplest and most effective
methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes.
A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital
and analog grounds, paying attention to the flow of the ground current.
To reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. If it
is not possible to keep them separate, it is much better to cross the sensitive trace perpendicular as opposed
to in parallel with the noisy trace.
Keep the length of input traces as short as possible. Always remember that the input traces are the most
sensitive part of the circuit.
Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce
leakage currents from nearby traces that are at different potentials.

(1) 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.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
