Electrical Characteristics

5.1

Absolute Maximum Ratings

Stresses beyond those listed in this section may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at these or other conditions beyond those indicated in

the operational sections of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

Note:

–

If VPIN is lower than GND-0.6V, then a current limiting resistor is required. The negative DC

injection current limiting resistor is calculated as R = (GND-0.6V – Vpin)/ICn.

–

If VPIN is greater than VDD+0.6V, then a current limiting resistor is required. The positive DC

injection current limiting resistor is calculated as R = (Vpin-(VDD+0.6))/ICn.
