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 under which the

device operates correctly. Operating ratings do not imply ensured performance limits. For specified performance limits and associated

test conditions, see the Electrical Characteristics.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

(3)

The human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin.

(4)

At elevated temperatures, devices must be derated based on package thermal resistance. The device in the SOT-23-3 package must be

derated at 4mW/°C at ambient temperatures above 70°C. The device has internal thermal protection.
