The q 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.
