It is optimal for use on Interfaces that utilize – TerminatedInputs Society of Automotive Engineers (SAE) J1708 – SHORTEDInputs ElectricalStandard. • OptimalforUseinSAEJ1708Interfaces The device is similar to standard TIA/EIA-485 • CompatiblewithPopularInterfaceStandards: transceivers, but differs in enabling scheme. The Driver's Input is normally externally tied LOW, thus – TIA/EIA-485andTIA/EIA-422-A providing only two states: Active (LOW), or Disabled – CCITTRecommendationV.11 (OFF). When the driver is active, the dominant mode • Bi-DirectionalTransceiver is LOW, conversely, when the driver is disabled, the busispulledHIGHbyexternalbiasresistors. – DesignedforMultipointTransmission • WideBusCommonModeRange The receiver provides a FAILSAFE feature that ensures a known output state when the Interface is in – (−7Vto+12V) the following conditions: Floating Line, Idle Line (no • AvailableinPDIPandSOICPackages active drivers), and Line Fault Conditions (open or short). The receiver output is HIGH for the following conditions: Open Inputs, Terminated Inputs (50Ω), or Shorted Inputs. FAILSAFE is a highly desirable feature when the transceivers are used with AsynchronousControllerssuchasUARTs.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
