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

Absolute Maximum Ratings indicate 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 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 100 pF capacitor discharged through a 1.5 k
Ω resistor into each pin.

Absolute Maximum Ratings indicate 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 conditions,
see the Electrical Characteristics.
Electrical Characteristics
Specifications with standard typeface are for TJ = 25°C, and those in bold face type apply over the full Operating Temperature
Range (TJ = -40°C to +125°C). Minimum and Maximum limits are ensured through test, design or statistical correlation.
Typical values represent the most likely parametric norm at TJ = 25°C and are provided for reference purposes only. VCC =
3.3V, unless otherwise specified.

Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods. The limits are used to calculate TI's Average Outgoing Quality Level (AOQL).
