NOTES:
1. Float condition occurs when maximum output current becomes less than I
LO
in magnitude. Float delay is not 100%
tested.
2. These inputs are allowed to be asynchronous to CLK2. The setup and hold specifications are given for testing purposes
to assure recognition within a specific CLK2 period.
3. These are not tested. They are guaranteed by design characterization.
4. Tested with CL set at 50 pF. See Figures 7 and 8 for load capacitance derating curve.
5. Minimum time not 100% tested.
