Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: For operation in ambient temperatures above 25C, the device must be derated based on a 150C maximum junction temperature and a package thermal
resistance of 110C/W, junction to ambient.
Note 3: ESD susceptibility test uses the “human body model, 100 pF discharged through a 1.5 k
resistor”.
Note 4: Typicals are at TJ = 25C and represent the most likely parametric norm.
Note 5: Tested Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 6: Relative difference between the input clamp voltage and the minimum input voltage which produces a horizontal output pulse.
Note 7: Careful attention should be made to prevent parasitic capacitance coupling from any output pin (Pins 1, 3, 5 and 7) to the RSET pin (Pin 6).
Note 8: Delay time between the start of vertical sync (at input) and the vertical output pulse.
