__________________________________________Typical Operating Characteristics

(RISET = 39k

Ω, TA = +25°C, unless otherwise noted.)

TIMING CHARACTERISTICS (Figure 2) (continued)

(V+ = 2.5V to 5.5V, TA = TMIN to TMAX, unless otherwise noted.) (Note 1)

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.
