C and represent the most likely parametric norm.
Note 4:
Tested Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 5:
Relative difference between the input clamp voltage and the minimum input voltage which produces a horizontal output pulse.
Note 6:
Careful attention should be made to prevent parasitic capacitance coupling from any output pin (Pins 1, 3, 5, and 7) to the R
SET
pin (Pin 6).
Note 7:
Delay time between the start of vertical sync (at input) and the vertical output pulse.
