NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3, 25°C ambient.
3. This parameter is guaranteed but not tested.
4. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
5. VOH = VCC - 0.6V at rated current.

NOTES:
1. See test circuits and waveforms.
2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. tPLH, tPHL, tSK(P), and tSK(O) 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.
5. Skew measured between all outputs under identical transitions and load conditions.
6. Skew measured is difference between propagation delay times tPHL and tPLH of same output under identical load conditions.
7. Part to part skew for all outputs given identical transitions and load conditions at identical VCC levels and temperature.
8. Airflow of 1m/s is recommended for frequencies above 133MHz.
