4. Electrical Characteristics
4.1 Disclaimer
All typical values are measured at T = 25°C and V
DD
= 3V unless otherwise specified. All minimum and
maximum values are valid across operating temperature and voltage unless otherwise specified.
Typical values given should be considered for design guidance only, and actual part variation around
these values is expected.
4.2 Absolute Maximum Ratings
Stresses beyond those listed in this section may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or other conditions beyond those indicated in
the operational sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

is lower than GND-0.6V, then a current limiting resistor is required. The negative DC
injection current limiting resistor is calculated as R = (GND-0.6V – V

4.3 General Operating Ratings
The device must operate within the ratings listed in this section in order for all other electrical
characteristics and typical characteristics of the device to be valid.
