Notes:
1. Functional operation above the absolute maximum stress ratings is not implied.
2. Static-sensitive device. Store only in conductive containers. Handling personnel and equipment should be grounded to prevent damage from static
discharge.
3. Switching times guaranteed by design.
4. Specification for packaged product only.
