Caution: Do not remove the device from (or insert it into) a socket or board that has VPP or VCC applied.
Notes:
1. VCC must be applied simultaneously or before VPP, and removed simultaneously or after VPP.
2. This parameter is sampled and not 100% tested.
3. Switching characteristics are over operating range, unless otherwise specified.
4. See Figure 3 and Table 1 for test specifications.
