Connect a capacitor to generate the V
sawtooth wave.
Connect a capacitor to hold the AGC
voltage which maintains the V
sawtooth wave at a constant
amplitude.
V pulse output pin.
polarity pulse 3 to 3.5 H width is
output from this pin.
H drive output pin. This pin is output
at the open collector.
X-ray protection circuit input pin.
When a pulse with a width of 7 V or
more is input, HD output becomes low
and R, G and B outputs are blanked.
This status is maintained until the
power supply is turned off.
High level: 4.5 V
Low level: 0 V
Vilmax = 2.4 V
Vihmin = 3.0 V
