ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. V
+ = 2.7V, V– = GND = 0V, unless otherwise specified.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Guaranteed by Design.
Note 3: Leakage current with a single 2.7V supply is guaranteed by
correlation with the
±5V leakage current specifications.
Note 4: Timing specifications with a single 2.7V supply are guaranteed by
correlation with the
±5V timing specifications.
