Revision 1.0 Publication Release Date: June, 2000
- 8 -
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. AC TESTING CONDITIONS
Output Reference Level
Output Load
Input Signal Levels
Transition Time (Rise and Fall) of Input Signal
Input Reference Level

7. Transition times are measured between V
IH
and V
IL
.
8. t
HZ
defines the time at which the outputs achieve the open circuit condition and is not referenced to output level.
