AC CHARACTERISTICS
NOTES:
1. Clock period and skew are measured on the rising edge at 1.5V.
2. t
3. t
4. t
5. Duty cycle should be tested with a 50/50% input.
6. Over MIN (20pF) to MAX (30pF) discrete load, process, voltage, and temperature.
7. Input edge rate for these tests must be faster than 1 V/ns.
8. Calculated at minimum edge rate (1.5ns) to guarantee 45/55% duty cycle at 1.5V. Pulsewidth is required to be wider at the faster edge to
9. All typical values are at V
10. Typical is measured with MAX (30pF) discrete load.
11. Typical is measured with MIN (20pF) discrete load.
