Notes:

2. See the last page of this specification for Group A subgroup testing information.

3. Test no more than one output at a time for not more than one second.

4. Outputs open. Tested at Frequency = 20 MHz.

5. Tested initially and after any design or process changes that may affect these parameters.

6. CL = 30 pF for all AC parameters except for tOHZ.

7. CL = 5 pF for tOHZ.
