DC Electrical Characteristics (Voltages referenced to GND)

1.  Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may

reduce device reliability. 2. Measured in plastic package at 25°C, results in die form are dependent on die attach and assembly method.

2. Essentially independent of

VTH, VTRIG,VRESET voltages.
