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
1.4V/1.4V
Output Load
See diagram below
Input Signal Levels
2.4V/0.4V
Transition Time (Rise and Fall) of Input Signal
2 nS
Input Reference Level
1.4V
50 ohms
1.4 V
AC TEST LOAD
Z = 50 ohms
output
50pF
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.
