Note 1: All parameters tested at TA =+25°C. Specifications over temperature are guaranteed by design.

Note 2: Guaranteed by design.

Note 3: A master device must provide a hold time of at least 300ns for the SDA signal (referred to VIL of the SCL signal) in order to

bridge the undefined region of SCL’s falling edge.

Note 4: CB = total capacitance of one bus line in pF. tR and tF measured between 0.3V+ and 0.7V+.

Note 5: ISINK

≤ 6mA. CB = total capacitance of one bus line in pF. tR and tF measured between 0.3V+ and 0.7V+.

Note 6: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.

DC ELECTRICAL CHARACTERISTICS (continued)

(V+ = 3V to 5.5V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at V+ = 5V, TA = +25°C.) (Note 1)
