(*1) When using this device at above Ta=25℃, the power dissipation decreases by 15.9mV per 1℃ rise.
(*2) This IC is weak against static electricity and surge impulse. Please take counter measure to meet, if
necessary.
(*3) This IC is not proofed enough against a strong E-M field by CRT which mau cause function error
and/or poor characteristics. Keeping the distance from CRT to the IC longer than 20cm, or if cannot,
placing shield metal over the IC, is recommended in an application.

The measure circuit against over modulation stops the
APC in detecting the over modulation, in order to avoid
folding the detected signal. It may cause, however,
malfunction against the phase modulated RF signals.
So evaluate carefully in using this function.

Standard vertical frequency
The read bus flags indicate that a certain signal is
detected at the moment. But reliability of detection
result is not so accurate if checking only one flag, that
confirming several flags, which means similar result
by each other, at the same time is recommended.
