SNVS387C – SEPTEMBER 2005 – REVISED MARCH 2013

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.

Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which

the device is intended to be functional, but does not ensure specific performance limits. For ensured specifications and 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)

Maximum recommended operating voltage not to exceed VCC - 2V or 5V, whichever is lower.

(4)

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

Ω resistor into each pin.
