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.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) Human body model, 100pF discharged through a 1.5kΩ resistor.
(4) Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage, then
discharged directly into the IC with no external series resistor (resistance of discharge path must be under 50 Ohms).
(5) The NGY0010A or NHD0010A package has its Exposed−DAP soldered to an exposed 2in² area of 1oz printed circuit board copper.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
(2) All voltages are measured with respect to the ground pin, unless otherwise specified.
(3) Typical specifications are specified at +25°C and represent the most likely parametric norm.
(4) Tested limits are ensured to TI's AOQL (Average Outgoing Quality Level). Datasheet min/max specification limits are ensured by design,
test, or statistical analysis.
