Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

Human Body Model (HBM)
2.0 kV per JEDEC standard: JESD22A114.
Machine Model (MM)
200 V per JEDEC standard: JESD22A115.
2. The maximum package power dissipation limit must not be exceeded.
