Note1: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are

stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recom-

mended operating conditions" is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device

reliability.

Note : ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which

are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for

MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen

free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by

weight).
