INPUT SIGNAL
NOTE HOW TO USE THIS IC
1. R, G, B input signal is 0.7V
2. H, V input is 5.0V TTL type.
3. Input signal with sufficient low inpedance to input terminal.
4. The terminal of H, V output pin are shown as Fig.1. It is possible
to reduce rise time by insert the resister between Vcc line and H, V
output Pin, but set the value of resister in order that the current is
under 7.5mA. Setting the value of R is more than 2k
Fig.1.
5. The terminal of R,G,B output pin (Pin 25, 28, 31). It is possible to
add a pull-up resister according as drive ability. but set the value of
resister in order that the current is under 10mA. Setting the value of
R is more than 500

When GND : Signal output from input 1
When OPEN : Signal output from input 2
