NOTES:
1. For all switching characteristics, the input pulse levels are 0.4V to 2.4V. Timing measurements are made at 2V for logic high and 0.8V for logic low.
(Reference AC testing waveform)
2. Common test conditions apply for tdis except during programming.
3. Value calculated from 0.5V delta to measured output level.
