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 indicate conditions under

which of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and

associated test condition, see the Electrical Characteristics tables.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

(3)

The absolute maximum specification of the 'Switch Voltage to Ground' applies to DC voltage. An extended negative voltage limit of -8V

applies to a pulse of up to 20 ns, -6V of 60 ns and -3V of up to 100 ns.

(4)

ESD was applied using the human-body model, a 100pF capacitor discharged through a 1.5 k

Ω resistor into each pin.
