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.
