Symbol Parameter Conditions Typ (Note 4) Units t PHL Propagation Delay (High to Low) Input Overdrive =10 mV 600 ns Input Overdrive =100 mV 200 ns t PLH Propagation Delay (Low to High) Input Overdrive =10 mV 450 ns Input Overdrive =100 mV 300 ns Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in- tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical characteristics. Note 2: : Human body model, 1.5k Ω in series with 100 pF. Machine model, 200Ω in series with 100 pF. Note 3: The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max) -TA)/θJA. All numbers apply for packages soldered directly into a PC board. Note 4: Typical Values represent the most likely parametric norm. Note 5: All limits are guaranteed by testing or statistical analysis. www.national.com 4 |
