DF
is defined as the time at which the output becomes an open circuit and data is no longer driven.
2. AC electrical parameters for programmng operations are not tested. These are guaranteed by design.
3. Test Conditions:
- Input pulse levels
0.45V/2.4V
- Input rise and fall times
< 20 ns
- Referenced levels for measuring timng
