1. TCYCLE in this spec is 1/Frequency at which the particular output is running.
2. The TPD specification’s min/max values may shift closer to zero if a larger pullup resistor is used.
3. Under equally loaded conditions and at a fixed temperature and voltage.
4. With VCC fully powered–on, and an output properly connected to the FEEDBACK pin. tLOCK maximum is with C1 = 0.1

5. The tPZL, tPHZ, tPLZ minimum and maximum specifications are estimates, the final guaranteed values will be available when ‘MC’ status is
reached.
