Enable Pin Logic Input. Applying a logic HIGH voltage signal enables the part. A logic LOW

voltage signal places the the device in shutdown.

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 indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed

performance limits and associated test conditions, 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)

All voltages are with respect to the potential at the GND pins.

For detailed information on soldering requirements and recommendations, please refer to National Semiconductor's Application Note

1187 (AN-1187): Leadless Leadframe Package (LLP).

(6)

The Human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin. The machine model is a 200pF

capacitor discharged directly into each pin. MIL-STD-883 3015.7
