NOTES:
1.
Operation exceeds "ABSOLUTE MAXIMUM RATING" may cause permanent damage to the devices.
2.
All voltages are referenced to V
SS
3.
These parameters depend on the cycle rate and listed values are measured at a cycle rate with the minimum values of
t
CK
and t
RC
.
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.
