SL621 Datasheet SYNC (Pin 4): Synchronization Input. The LT1 505 can be synchronized to an external clock with pulses that have duty cycles between 10% and 95%. An internal one shot that istriggered on the rising edge ofthe sync pulse makes this input insensitive to the duty cycle of the sync pulse. The input voltage range on this pin is OV t0 20V. This pin can float if not used.
