Note :
1. ICC1 depends on output loading and cycle rates.
Specified values are obtained w ith the output open.
Input signals are changed only one time during tCK(min)
2. ICC4 depends on output loading and cycle rates.
Specified values are obtained w ith the output open.
Input signals are changed only one time during tCK(min)
3. Input signals are changed only one time during tCK(min)
4. Standard pow er version.
5. * Low pow er version.
