ELECTRICAL CHARACTERISTICS (continued)

= +1.62V to +3.6V, T

= -40NC to +85NC, unless otherwise noted. Typical values are at V

= +3.3V, T

= +25NC.) (Notes 3, 4)

Note 3: All parameters are tested at T

= +25NC. Specifications over temperature are guaranteed by design.

Note 4: All digital inputs at V

or GND.

Note 5: Guaranteed by design.

Note 6: A master device must provide a hold time of at least 300ns for the SDA signal (referred to V

of the SCL signal) to bridge

the undefined region of SCL’s falling edge.

Note 7: C

= total capacitance of one bus line in pF. t

and t

measured between +0.8V and +2.1V.

Note 8: I

SINK

P 6mA. C

= total capacitance of one bus line in pF. t

and t

measured between +0.8V and +2.1V.

Note 9: Input filters on the SDA, SCL, and AD0 inputs suppress noise spikes less than 50ns.
