ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(V

DD

= +2.7V to +5.5V, T

A

= -40°C to +125°C, unless otherwise noted. Typical values are specified at T

A

= +25°C and V

DD

= +5V,

unless otherwise noted.)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:

See Temperature Accuracy histograms in

Typical Operating Characteristics

.

Note 2:

Guaranteed by design. Not production tested.

Note 3:

Limit maximum start pulse at 1ms to avoid timing overlap.

Note 4:

If no reset pulse is applied.
