Note: 1. Complies with JEDEC JEP95 MO-220I, variant WJJD-5 except external paddle nominal dimensions.
2. From the bottom view, the pin #1 indicator may be either a 45-degree chamfer or a half-circle notch.
3. The external paddle is electrically connected to the die back-side and possibly to certain VSS leads.
This paddle should be soldered to the PC board; it is suggested to connect this paddle to the VSS of the unit.
Connection of this paddle to any other voltage potential will result in shorts and/or electrical malfunction of the device.
4. Untoleranced dimensions are nominal target dimensions.
5. All linear dimensions are in millimeters (max/min).
