NOTES:
3. Power-up of the device requires all VCELL1, VCELL2, VCELL3, and VCC to be above the limits specified.
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. Limits established by characterization and are not production tested.
6. Maximum output capacitance = 15pF
Operating Specifications
All Specifications Apply to Both the ISL9216 and ISL9217 Separately Over the Recommended Operating
Conditions, Unless Otherwise Specified.
