TTL and CMOS input compatible
when control port (Pin4)connect a
capacitance.The capacitance is
between 1000pf-10000pf depends
upon TTL cycle .Logic1(+3V～+5V):on;
Logic 0(0V):off.

Application notes
1. ESD sensitive device observe handling precoution
2. Precaution should be taken to avoid the video transients
during switching period
3. The device should be properly grounded to insure
the isolation performance
TTL and CMOS input compatible
as below application.Logic1
(+3V～+5V):on;Logic0(0V):
Off.DC voltage should be equal
to control level(TTL OR CMOS)
