CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
5. Due to the SCR structure inherent in the CM0S process used to fabricate these devices, connecting any terminal to a voltage greater than VDD or less
than VSS may cause destructive device latch-up. For this reason it is recommended that no inputs from sources operating on a different power supply
be applied to the device before its own supply is established, and when using multiple supply systems the supply to the ICM7218 should be turned
on first.
6. JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
7. For JC, the “case temp” location is the center of the ceramic on the package underside.
Electrical Specifications VDD = 5V, VSS = 0V, TA = +25°C, display diode drop = 1.7V
