Recommended Pad LayoutNotes
1. JEDEC termination code (e4). Barrier-plating isnickel [Ni] with gold [Au] flash plate.
2. Terminations #2, #4 and the metal lid areconnected internally. End user may connect thesepins to circuit ground for EMI suppression.
3. Due to package variability, the pad chamfer on thebottom could be located on Pin 2 or 4 in a given lot.
Layout orientation should be based on the top view
[marking side], as indicated in package drawing.
The chamfer location does not affect the electricalperformance of the device.
4. Reflow conditions per JEDEC J-STD-020; +260°C
maximum, 20 seconds.
5. MSL = 1.
