10. This specification indicates the guaranteed maximum frequency at which a state machine configuration with external feedback can operate.
11. This specification indicates the guaranteed maximum frequency at which the device can operate in data path mode.
12. This specification indicates the guaranteed maximum frequency at which a state machine configuration with internal only feedback can operate.
13. This parameter is calculated from the clock period at f

Min. times are tested initially and after any design or process changes that may affect these parameters.
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 V
