The Standardspecifiesthe interconnectto be a singletwisted-paircable(shieldedor unshielded)with120-Ω characteristicimpedance (Zo).Resistorsequaltothecharacteristicimpedance ofthelineterminatebothends of thecabletopreventsignalreflections.Unterminateddrop-linesconnectnodes tothebus and shouldbe keptas shortas possibletominimizesignalreflections. Connectors,whilenotspecifiedby theISO 11898 standard,shouldhave as littleeffectas possibleon standard operatingparameterssuch as capacitiveloading.Althoughunshieldedcableisused inmany applications,data transmissioncircuitsemploying CAN transceiversare usuallyused in applicationsrequiringa rugged interconnectionwitha wide common-mode voltagerange.Therefore,shieldedcableisrecommended inthese electronicallyharsh environments,and when coupledwiththe –2-V to 7-V common-mode range of tolerable groundnoisespecifiedinthestandard,helpstoensuredataintegrity.The HVD251 extendsdataintegritybeyond thatofthestandardwithan extended–7-V to12-V rangeofcommon-mode operation.

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) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
