REMOTE CONTROL ENCODER

DESCRIPTION

SC5104 is a remote control encoder paired with SC8206 utilizing

CMOS technology. Using a special coding technique, SC5104

increases noise immunity to a very great extent. SC5104 has a

maximum of 8 input channel. Its high performance features makes

SC5104 a must in every fan and other electrical home appliance

remote control application.

SC5104 adopt 16-DIP package.

FEATURE

* CMOS techonogy

* High noise immunity

* Wide range of voltage: Vcc=2.2 ~ 5.0 V

* LED indicator

* Transmits signal of maximum 8 channels

* 2 bits custom code options available

* Key-in oscillation, reduce static current dissipation.
