Applicat ion Notes
1. ESD obs erve handl ing preca ntions .Over time
soldering may cause Perm anent damage
2. The high leve l of TTL con trol signal sho uld
be higher than 3.5V to provi de
3. When higher oper ating frequen cy and isol ation
and required,isolation meas ures should be used
betwee n input and output ports to abtain the
guaranteed performance
4. The dec oupl ing cap aci tors(>0.1uF and 10000 pF)
are requi red to filter the iterferenc e on the
power por t
5. See ass embly sec tion for mount ing method
