3. Power up of the device requires all V
4. The device provides an internal hold time of at least 300ns for the SDA signal to bridge the unidentified region of the falling edge of SCL.
5. Typical +125°C ±10%, based on design and characterization data.
6. Typical 5Ω ±2Ω, based on design and characterization data.
7. Maximum output capacitance = 15pF.
