9.0 DC and AC Specification

Absolute Maximum Ratings

Recommended Operating Conditions

Note: Absolute maximum ratings are those values beyond which the safety of the device can be guaranteed. These ratings are not meant to imply that the

device should be operated at these limits.

A = 0 °C to 70 °C, VDD = 5V ±5%, unless otherwise specified

Note 1: This parameter is guaranteed by design and is not tested.

Note 2: The operation in reduced mode is not guaranteed below 300 mV.
