Handling Procedure

Stresses above these listed maximum ratings may cause

permanent damage to the device. Exposure beyond specified

electrical characteristics may affect device reliability

Electrical parameters and functionality are not guaranteed

when the circuit is exposed to light.

This device has built-in protection against high static

voltages

or

electric

fields;

however,

anti-static

precautions should be taken as for any other CMOS

component.

Unless

otherwise

specified,

proper

operation can only occur when all terminal voltages are

kept within the supply voltage range.

Note 1 : Maximum voltage is defined by forcing 10mA on Coil1-Coil2

Note 2 : The circuit is not functional below the POR-level
