Limits apply to TA = 25°C. Symbol Parameter Conditions LM48822 Units (Limits) Typical (Note 6) Limit (Note 7) t 1 SCL Period 2.5 μs (min) t 2 SDA Setup Time 100 ns (min) t 3 SDA Stable Time 0 ns (min) t 4 Start Condition Time 100 ns (min) t 5 Stop Condition Time 100 ns (min) V IH Input High Voltage 1.3 V (min) V IL Input Low Voltage 0.4 V (max) Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum RatingsRatings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified Note 2: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed. Note 3: maximum allowable power dissipation is P DMAX = (TJMAX - TA) / θJA or the number given in Absolute Maximum Ratings, whichever is lower. Note 4: Human body model, applicable std. JESD22-A114C. Note 5: Machine model, applicable std. JESD22-A115-A. Note 6: Typical values represent most likely parametric norms at T A = +25ºC, and at the Recommended Operation Conditions at the time of product characterization and are not guaranteed. Note 7: Datasheet min/max specification limits are guaranteed by test or statistical analysis.
