Electrical specifications

2.1

Operating range

Within the operating range the part operates as specified and without parameter deviations. The device may not

operate properly if maximum operating conditions are exceeded.

Once taken beyond the operative ratings and returned back within, the part will recover with no damage or

degradation.

The voltages are referred to ground, and currents are assumed positive, when the current flows into the pin.
