Output skew: skew between outputs of all banks of
same package (inputs tied together)
Pulse skew: skew between opposite transitions
of same output (|tPHL -– tPLH|)
Package skew: skew between outputs of different
packages at same power supply voltage,
temperature, package type and speed grade

NOTES:
1. See test circuits and waveforms.
2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. tPLH, tPHL, tSK(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 VCC, operating temperature and process parameters. These propagation delay limits do not imply skew.
