AC ELECTRICAL CHARACTERISTICS OVER THE
OPERATING TEMPERATURE AND SUPPLY VOLTAGE RANGE
NOTES:
1. Transition is measured 500mV from Low or High-impedance voltage Output Test Load (Figure 2).
2. Com'l Only, 0 C to +70 C temperature range. PLCC and TQFP package.
3. “X” in part numbers indicates power rating (SA or LA).
4. This parameter is guaranteed by device characterization, but is not production tested.
5. Not available in DIP packages.
