IN
= 3V ● 0.2 2 µA
The ● denotes specifications which apply over the full operating
temperature range.
Note 1: Absolute maximum ratings are those beyond which the safety of
the device may be impaired.
Note 2: Guaranteed by design.
Note 3: Leakage current with a single 3V supply is guaranteed by
correlation with the leakage current of the ±5V supply.
Note 4: Timing specifications with a single 3V supply is guaranteed by
correlation with the timing specifications of the ±5V supply.
