Typical Application
Figure 1.
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.

Soldering process must comply with Reflow Temperature Profile specifications. Refer to http://www.ti.com/lit/SNOA549.
(4)
(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its rated operating conditions.
(2) When the input voltage (V
I
) at any pin exceeds the power supplies (V
I
< GND or V
I
> +V
S
) the current at that pin should be limited to 5
mA. The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input
current of 5 mA to four.
(3) Human body model, 100 pF discharged through a 1.5 k?resistor. Machine model, 200 pF discharged directly into each pin.
(4) Reflow temperature profiles are different for lead-free and non-lead-free packages.
