NOTES:

1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are

exceeded. Functional operation should be restricted to RECOMMENDED

OPERATING CONDITIONS. Exposure to higher than recommended voltages for

extended periods of time could affect device reliability.

2. This is a steady–state DC parameter that is in effect after the power supply has

achieved its nominal operating level. Power sequencing is not necessary.

3. Power dissipation capability is dependent upon package characteristics and use

environment. See Package Thermal Characteristics.

NOTES:

1. Junction temperature is a function of on–chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient

temperature, air flow, board population, and board thermal resistance.

2. Per SEMI G38–87.

3. Indicates the average thermal resistance between the die and the printed circuit board.

4. Indicates the average thermal resistance between the die and the case top surface via the cold plate method (MIL SPEC–883

Method 1012.1).

This device contains circuitry to protect the

inputs against damage due to high static volt-

ages or electric fields; however, it is advised

that normal precautions be taken to avoid

application of any voltage higher than maxi-

mum rated voltages to this high–impedance

circuit.
