3 TICall TI-25 to 85( ~ ) (RoHS& no Sb/Br)Call TILevel-1-NA-UNLIM-25 to 85( ~ ) (1) The marketing status values are defined as follows:ACTIVE: Product device recommended for new : TI has announced that the device will be discontinued, and a lifetime-buy period is in : Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new : Device has been announced but is not in production. Samples may or may not be : TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check for the latest availabilityinformation and additional product content : The Pb-Free/Green conversion plan has not been (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 thatlead not exceed by weight in homogeneous materials.

4 Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-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 betweenthe die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined (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 by weightin homogeneous material) (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.

5 If a line is indented then it is a continuationof the previous line and the two combined represent the entire Device Marking for that OPTION 2 (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 finishvalue exceeds the maximum column width.
