ELECTRICAL CHARACTERISTICS
The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T
A
= 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.
