Application Notes
1. ESD observe handling precantions.Overtime
soldering may cause Permanent damage
2. The high level of TTL control signal should
be higher than 3.5V and 2ï½3mA to provide
3. When higher operating frequency and isolation
and required,isolation measures should be used
between input and output ports to abtain the
guaranteed performance
4. The decoupling capacitors(>0.1uF and 10000pF)
are required to filter the iterference on the
power port
