description
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
