Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2: 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 de-
grade when the device is not operated under the listed test conditions.
Note 3: All voltages are measured with respect to GND, unless otherwise specified.
Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
allowable power dissipation at any elevated temperature is P
this device, T
Note 5: Human Body model, 100 pF capacitor discharged through a 1.5 k
Note 6: Typical specifications are at T
Note 7: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8: The standard deviation, , of the flyback pulse period is measured with a HP 53310A Modulation Domain Analyzer. Peak-to-peak jitter of the flyback pulse
is defined by 6 .
Note 9: A positive phase value represents a phase lead of the flyback pulse peak with reference to the center of H sync.
Note 10: The duty cycle is measured under the conditions of free run with I
and the turn off delay of the H deflection output transistor respectively.
