Notes:
1. Operation exceeds “Absolute Maximum Ratings” may cause permanent damage to the devices.
2. All voltages are referenced to VSS
3. These parameters depend on the cycle rate and listed values are measured at a cycle rate with the
4. These parameters depend on the output loading conditions. Specified values are obtained with
