1. Logic input levels compatible with 5V CMOS logic.

2. All data inputs are commuted at 10MHz

3. See Figure 6: Test configuration

4. This parameter is measured during ST’s internal qualification which includes temperature characterization on standard and

corner batches of the process. This parameter is not tested on the part.
