Notes:

1. Timings are measured from 1.5V of the clock to 1.5V of the signal.

2. Capacitive load for all output timings is 50pF.

3. Data Output timing applies to all signal pins whether tristate I/O or output only.

4. Setup and Hold parameters apply to all signal pins whether tristate I/O or input only.
