Note: Do not apply to pins 11 and 22 a voltage higher than the REG & VCC2 voltages of pins 8 and 20.
* Do not use Y/C-MIX for cases other than composite/S.
* For composite, the chroma signal is entered with pin 6 in C connection, the composite signal is entered with pin 3 clamped, and the Y signal is entered with pin 9
clamped. However, for S, Pin 3 has no input.
For component, the B-Y/R-Y signal is entered with pins 3 and 6 clamped to pedestal and the Y signal is entered with pin 10 clamped.
For base band, the RGB signal is entered with pins 3, 6, and 10 clamped.
Do not use Pins 11 and 22 in the OPEN state.
