DESCRIPTION/ORDERING INFORMATION
The AM26LV31C and AM26LV31I are BiCMOS quadruple differential line drivers with 3-state outputs. They are
designed to be similar to TIA/EIA-422-B and ITU Recommendation V.11 drivers with reduced supply-voltage
range.
The devices are optimized for balanced-bus transmission at switching rates up to 32 MHz. The outputs have very
high current capability for driving balanced lines such as twisted-pair transmission lines and provide a high
impedance in the power-off condition. The enable function is common to all four drivers and offers the choice of
active-high or active-low enable inputs. The AM26LV31C and AM26LV31I are designed using Texas Instruments
proprietary LinIMPACT-C60™ technology, facilitating ultra-low power consumption without sacrificing speed.
These devices offer optimum performance when used with the AM26LV32 quadruple line receivers.
The AM26LV31C is characterized for operation from 0°C to 70°C. The AM26LV31I is characterized for operation
from –45°C to 85°C

(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.

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)

warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily
performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should
provide adequate design and operating safeguards.
