Electrical Specifications
Absolute Maximum Ratings
This device contains circuitry to protect the inputs against damage caused by high static voltages or
electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage
greater than maximum rated voltages to these high-impedance (Hi-Z) circuits.
The device also contains protection against external magnetic fields. Precautions should be taken to
avoid application of any magnetic field more intense than the maximum field intensity specified in the
maximum ratings.

1. H = high, L = low, X = don’t care
2. Hi-Z = high impedance
1. Permanent device damage may occur if absolute maximum ratings are exceeded. Functional operation
2. All voltages are referenced to V
3. Power dissipation capability depends on package characteristics and use environment.
should be restricted to recommended operating conditions. Exposure to excessive voltages or magnetic fields
could affect device reliability.
