NOTES:
1. Tested at maximum operating frequency and guaranteed by design characterization at lower operating frequencies.
2. These are not tested. They are guaranteed by characterization.
3. Tested with C
L
set at 50 pF. Timings are guaranteed with C
L
set at 75 pF.
4. Float condition occurs when maximum output current becomes less than I
LO
in magnitude. Float delay is not fully tested.
5. These inputs may be asynchronous to CLK2. The setup and hold specifications are given for testing purposes to ensure
recognition within a specific CLK2 period.
6. These specifications are for information only and are not tested. They are intended to assist the designer in selecting
memory speeds. For each wait state in the design add two CLK2 cycles to the specification.
