DESCRIPTION
UTC RBA5104 is a remote control encoder mainly used for
Fan remote control, air cleaner, humidifier, heater and other
electrical home appliance remote control application. 2 bits
custom code options and maximum 8 input channels offers great
freedom in application. UTC RBA5104 uses a special coding
technique to increase noise immunity to a very great extent.
„
FEATURES
* Wide operation voltage: VCC=2.2~4.0V
* Noise immunity technique
* 2 bits custom code
* 8 input channels maximum
* Uses 455kHz crystal oscillator
* Key-in oscillation, reduce static current dissipation.
* 38kHz carrier transmits output.
* LED indicates work state
