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) Maximum ratings indicate limits beyond which permanent damage may occur. Continuous operation at these limits is not intended and
should be limited to those conditions specified under DC electrical characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
DC SPECIFICATIONS
TA = -40°C to +85°C, V_CC = +2.97V to 5.5V, V_SS = 0V, unless otherwise specified.
Typical specifications are at TA=25°C, and represent most likely parametric norms at the time of product characterization.
The typical specifications are not ensured.
