Notes
11. The input pull-down circuit is stronger (50 K) when the input voltage is below V_IL and weak (1 M) when the input voltage is above V_IH.
12. Min V_CAP value guarantees that there is a sufficient charge available to complete a successful AutoStore operation. Max V_CAP value guarantees that the capacitor on
V_CAP is charged to a minimum voltage during a Power-Up RECALL cycle so that an immediate power-down cycle can complete a successful AutoStore. Therefore it
is always recommended to use a capacitor within the specified min and max limits. Refer application note AN43593 for more details on V_CAP options.
13. Maximum voltage on V_CAP pin (V_VCAP) is provided for guidance when choosing the V_CAP capacitor. The voltage rating of the V_CAP capacitor across the operating
temperature range should be higher than the V_VCAP voltage.
14. These parameters are guaranteed by design and are not tested.
