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

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) 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.
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)
