Notes:
5.
Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this datasheet. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
6.
The datasheet limits are not guaranteed if the device is operated beyond the operating ratings.
7.
Package thermal resistance assumes the exposed pad is soldered (or equivalent) to the device’
s most negative potential on the PCB. Ψ
JB
and θ
JA
values are determined for a 4-layer board at the still-air package thermal resistance, unless otherwise stated.
8.
The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
