Notes:
1. See test circuits and waveforms.
2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. t
PLH
and t
PHL
are production tested. All other parameters guaranteed but not production tested.
4. Propagation delay range indicated by Min. and Max. limit is due to V
CC
, operating temperature and process parameters. These propagation delay limits do not
imply skew.
5. Skew measured between all outputs under identical transitions and load conditions.
6. Skew measured is difference between propagation delay times t
PHL
and t
PLH
of same outputs under identical load conditions.
7. Part to part skew for all outputs given identical transitions and load conditions at identical V
CC
levels and temperature.
8. Airflow of 1m/s is recommended for frequencies above 133MHz.
9. This parameter is measured using f = 1MHz.
