• Manufacturer: WINBOND [Winbond]

NOTES:
Revision 1.0
1. Operation exceeds "ABSOLUTE MAXIMUM RATING" may cause permanent damage to the devices.
2. All voltages are referenced to V
3. These parameters depend on the cycle rate and listed values are measured at a cycle rate with the minimum values of
4. These parameters depend on the output loading conditions. Specified values are obtained with output open.
5. Power up sequence is further described in the "Functional Description" section.
6. AC TESTING CONDITIONS
7. Transition times are measured between V
