ABSOLUTE MAXIMUM RATINGS

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltages are

absolute voltages referenced to the LGND pin.

Operating Junction Temperature……………..0 to 150

Storage Temperature Range………………….-65

ESD Rating………………………………………HBM Class 1C JEDEC Standard

MSL Rating………………………………………2

Reflow Temperature…………………………….260
