Note 1: When placing the R

resistor and the 0.1
μ
F decoupling capacitor careful attention should be made to ensure that they are as close
as possible to pin 6. Care should also be taken to avoid parasitic capacitive coupling from any output pin (pins 1, 3, 5 and 7) to pin 6.
Note 2: Measured from slicing point of input falling edge to 50% point of composite sync falling edge.
