Limiting values

[1]

The following applies to Limiting values:

a) Stresses above those listed under Table 7 may cause permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any conditions other than those described in Table 8 “DC electrical characteristics”, Table 9 “AC

characteristics” and Table 10 “AC characteristics” of this specification are not implied.

b) This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive

static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
