Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which

operation of the device is intended to be functional. For ensured specifications and 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)

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

Ω resistor into each pin. 2kV for all pins. The HB, HO, and HS

pins are rated for 150V, machine model.

All limits are specified. All electrical characteristics having room temperature limits are tested during production with TA = 25°C. All hot

and cold limits are specified by correlating the electrical characteristics to process and temperature variations and applying statistical

process control.
