REMOTE CONTROL ENCODER
DESCRIPTION
The SC2268 is a remote control encoder utilizing CMOS
Technology specially designed for use with the SC2128. Using a
special coding technique, SC2268 increases noise immunity to a
very great extent. It is housed in 16-Pins DIP Package and has a
maximum of eight input channels. Its high performance features
makes SC2268 a must in every fan and other electrical home
appliance remote control application.
