(1)
Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
All voltage values are with respect to GND.
(3)
Absolute negative voltage on these pins must not go below –0.5 V.
(4)
Not more than one output should be shorted at a time, and duration of the short circuit should not exceed 1 ms.
(5)
The thermal data is based on using 1-oz copper trace with JEDEC 51-5 test board for PWP and JEDEC 51-7 test board for N.
(6)
The data is based on ambient temperature of 25
°C max.
(7)
The Human-Body Model is a 100-pF capacitor discharged through a 1.5-k
resistor into each pin.
