These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the
device is intended to be functional, but device parameter specifications may not be ensured. For specifications and test conditions, see
the Electrical Characteristics.
(2) This pin is internally pulled high and clamped at 8V typical. The absolute maximum and operating maximum rating specifies the input
level allowed for an external voltage source applied to this pin without triggering the internal clamp with margin.
(3) The maximum allowable power dissipation is a function of the maximum junction temperature, T
J_MAX
, the junction-to-ambient thermal
resistance, θ
JA
= 240°C/W, and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is
calculated using: P
D_MAX
= (T
J_MAX
- T
A
)/θ
JA
. Exceeding the maximum allowable power dissipation will cause excessive die temperature.
(4) The human body model is a 100 pF capacitor discharged through a 1.5kΩ resistor into each pin. The machine model is a 200pF
capacitor discharged directly into each pin. MIL-STD-883 3015.7
