(max.).
Not connected.
Subcarrier input
NTSCIPAL mode switching pin
BF
pulse monitoring output
Time constant which determines the
Y signal clamp
is
connected.
Composite sync signal input. Receives
it
at the
TTL
leveL
Not connected.
Power supply
of
circuit other than RGB, composite video and Y /C output
Pin to determine the internal reference current leveL
Internal reference voltage pin.
