2 E LECTRICAL C HARACTERISTICS
2.1 Absolute Maximum Ratings
Stress above the limits listed in the following table may cause permanent failure. Exposure to absolute ratings for
extended time periods may affect device reliability. The limiting values are in accordance with the Absolute
Maximum Rating System (IEC 134). All voltages are referenced to ground (GND).
