Note 1.

All voltage are measured with respect to the ground pin, unless otherwise specified.

Note 2.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical

specifications under particular test conditions which guarantee specific performance limits. This assumes that the device is within Operating

Ratings. Specifications are not guaranteed for parameters where no limit is given, however, the typical value is a good indication of device

performance.

Note 3.

The maximum power dissipation must be derated at elevated temperature and is dictated by TJMAX, ΘJA and the ambient temperature TA.

The maximum allowable power dissipation is PDMAX = (TMAX - TA)/ ΘJA . For the CM8662, TJMAX = 150℃. The typical junction-to-ambient

thermal resistance, when board mounted, is 170℃/W for package number M08A and is 107℃/W for package number N08E.

Note 4.

Human body model, 100pF discharged through a 1.5kΩ resistor.

Note 5.

Machine model, 200 pF - 240 pF discharged through all pins.
