Note 1:

Duration not to exceed 10 seconds, and no logic switching.

Note 2:

Referenced to Vss

Note 3:

Stresses above those listed under “ absolute maximum ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at these or any other conditions above those

indicated in the operating conditions section of this specification is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect the device reliability.

Note 4:

VDD level when absolute maximum current goes through coil inputs.

Note 5:

VDD level when absolute maximum voltage is across coil inputs.

Note 6:

protection circuitry.

Note 7:

Maximum allowed peak current of incoming RF signal.

Note 8:

TBD - To be determined.

HANDLING PROCEDURES

Although the device has built-in ESD protection, adherence to anti-static procedures for CMOS devices is required.
