NOTES:
7. AC tests performed with CL = 40pF, IOL = 2mA, and IOH = -400A. Input reference level CLK = 2.0V. Input reference level for all other inputs is
1.5V. Test VIH = 3.0V, VIHC = 4.0V, VIL = 0V, VILC = 0V.
8. Setup time requirement for loading of data on CIN0-9 to guarantee recognition on the following clock.
9. Controlled via design or process parameters and not directly tested. Characterized upon initial design and after major process and/or changes.
10. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
11. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
