ABSOLUTE MAXIMUM RATINGS

Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at

or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical

Characteristics at the test conditions specified

ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible

to damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage

of this device.

As per specifications IPC/JEDEC J-STD-020A and JEDEC A113-B, this product requires specific storage conditions prior to

surface mount assembly. It has been classified as having a Moisture Sensitivity Level of 2 and as such will be supplied in

vacuum-sealed moisture barrier bags.
