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.

If Military/Aerospace specified devices are required, please contact the TI 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 except HB, HO and HS

which are rated at 1.5kV.

Threshold

(1)

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

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

process control.

(2)

Typical specifications represent the most likely parametric norm at 25°C operation
