NOTES:
1. Transition is measured 0mV from Low or High-Impedance Voltage Output Test Load (Figure 2).
2. PLCC package only.
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. Industrial temperature: for specific speeds, packages and powers contact your sales office.
