The 3-state outputs have high-current capability for driving balanced lines such as twisted-pair or parallel-wire transmission lines, and they are in the high-impedance state in the power-off condition. The enable function is common to all four drivers and offers the choice of an active-high or active-low enable (G, G) input. Low-power Schottky circuitry reduces power consumption without sacrificing speed. 1 GND • 1A 1Y 1Z G 2Z 2Y 2A GND 1Y • • • • D, DB, N, NS, J, OR W PACKAGE (TOP VIEW) Meets or Exceeds the Requirements of ANSI TIA/EIA-422-B and ITU Operates From a Single 5-V Supply TTL Compatible Complementary Outputs High Output Impedance in Power-Off Conditions Complementary Output-Enable Inputs 2A • ORDERING INFORMATION PACKAGE (1) TA PDIP – N 0°C to 70°C –55°C to 125°C (1) ORDERABLE PART NUMBER TOP-SIDE MARKING Tube AM26LS31CN Tube AM26LS31CD Tape and reel AM26LS31CDR SOP – NS Tape and reel AM26LS31CNSR 26LS31 SSOP – DB Tape and reel AM26LS31CDBR SA31C CDIP – J Tube AM26LS31MJB AM26LS31MJB LCCC – FK Tube AM26LS31MFKB AM26LS31MFKB CFP – W Tube AM26LS31MWB AM26LS31MWB SOIC – D AM26LS31CN AM26LS31C Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.

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) Addendum-Page 1 PACKAGE OPTION ADDENDUM www.ti.com 15-Oct-2009 (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
