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 ORDERING INFORMATION PACKAGE (1) TA SOIC – D Tape and reel SOIC – NS Tape and reel SOIC – D Tape and reel SOIC – NS Tape and reel 0°C to 70°C –45°C to 85°C (1) ORDERABLE PART NUMBER AM26LV31CD AM26LV31CDR AM26LV31CNS AM26LV31CNSR AM26LV31ID AM26LV31IDR AM26LV31INS AM26LV31INSR TOP-SIDE MARKING AM26LV31C 26LV31 AM26LV31I 26LV31I Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
