NOTES:
1. See test circuits and waveforms.
2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. t
PLH
, t
PHL
, t
SK
(t) 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.
