V S/S pulse output pin
No problem occurs when current of
approx. 6 mA flows to internal part of the
IC. To improve the rising speed, connect
a resistance between power supplies.

Logic output pin for horizontal synchro-
nous signal
When pin 6 input signal is POSI, outputs
"L"; when NON, outputs "L"; and when
NEG, outputs "H".
Logic output pin for vertical synchronous
signal
When pin 8 input signal is POSI, outputs
"L"; when NON, outputs "L"; and when
NEG, outputs "H".
CLAMP TIMING pin
The clamp pulse width is determined
depending on the external resistance and
capacitance. As the resistance value and
capacitance value are larger, the clamp
pulse width is wider.
