Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. Pulse (

μsec) noise exceeding the above input voltage (VSS+12V) may cause damage to the IC.
