Notes:

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 AT17FxxA Programming Specification for procedural information.

5. Times given are per byte typical.
