ESD Warning

ESD (electrostatic discharge) sensitive device. Although the MX844 features proprietary ESD protection circuitry,

permanent damage may be sustained if subjected to high energy electrostatic discharges. Proper ESD precautions

are recommended to avoid performance degradation or loss of functionality.

Absolute

Maximum

Ratings

are

stress ratings. Stresses in excess of

these ratings can cause permanent

damage to the device. Functional

operation of the device at these or

any other conditions beyond those

indicated in the operational sections

of this data sheet is not implied.

Exposure

of

the

device

to

the

absolute maximum ratings for an

extended period may degrade the

device and affect its reliability.
