Conditions

Note 1:

The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable

junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the

maximum allowable power dissipation may cause the device operating junction temperature to exceed the

maximum 160°C rating. Sustained junction temperatures above 150°C can impact the device reliability

and OTP data retention.

1000 hour cumulative maximum for OTP data retention (typical).
