1. Preliminary specifications for military operating range only.
2. AC test lead = 50 pF.
3. Float delays are measured with 5 pF AC loads. Transition is measured ±200 mV from steady-state active levels.
4. See the AT17F Programming Specfication for procedural information.
5. The times given are per byte (typical).
