1. t
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 programming operations are not tested. These are guaranteed by design.
3. Test conditions:
- Input pulse levels
0.45V/2.4V
- Input rise and fall times
< 10 ns
- Output load
1TTL Fate + 100 pF (including scope and jig)
- Referenced levels for measuring timing
0.8V/2.0V
