Notes:
8. Min. times are tested initially and after any design or process changes that may affect these parameters.
9. This specification is guaranteed for all device outputs changing state in a given access cycle.
10. This parameter is measured as the time after OE pin or internal disable input disables or enables the output pin. This delay is measured to the point at which a previous HIGH
level has fallen to 0.5 volts below VOH min. or a previous LOW level has risen to 0.5 volts above VOL max.
11. This specification indicates the guaranteed maximum frequency at which a state machine configuration with external feedback can operate.
12. This specification indicates the guaranteed maximum frequency at which the device can operate in data path mode.
13. This specification indicates the guaranteed maximum frequency at which a state machine configuration with internal only feedback can operate.
14. This parameter is calculated from the clock period at fMAX internal (1/fMAX3) as measured (see Note 7 above) minus tS.
