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 are conditions for which the
device is intended to be functional, but device parameter specifications may not be guaranteed. For ensured specifications and test
conditions, see the Electrical Characteristics. All voltages are with respect to the potential at the GND pin, unless otherwise specified.
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at T J = 165°C (typ.) and
disengages at T J = 145°C (typ).

ELECTRICAL CHARACTERISTICS
Limits in standard type face are for T J = 25°C and those with boldface type apply over the full Operating Temperature
Range ( T J = ? 40°C to +125°C). Minimum and Maximum limits are specified through test, design, or statistical correlation.
Typical values represent the most likely parametric norm at T J = +25oC, and are provided for reference purposes only.
