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 indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the 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) Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std. JESD22-A115-A (ESD MM std. of
JEDEC)Field-Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC).
(4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C.
(5) The maximum power dissipation is a function of T_J(MAX), θ_JA, and T_A. The maximum allowable power dissipation at any ambient
temperature isP_D = (T_J(MAX) − T_A)/θ_JA. All numbers apply for packages soldered directly into a PC board.

Unless otherwise specified, all limits specified for T_J = 25°C, V⁺ = 2.7V to 5V, V^− = 0V, V_CM = V_O = V⁺/2. Boldface limits apply
at the temperature extremes.

(1) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not specified on shipped
production material.
(2) All limits are specified by testing or statistical analysis.
(3) CMRR measured at V_CM = 0V to 2.5V and 2.5V to 5V when V_S = 5V, V_CM = 0.2V to 1.35V and 1.35V to 2.7V when V_S = 2.7V. This
eliminates units that have large V_OS at the V_CM extremes and low or opposite V_OS at V_CM = V_S/2.
