UNISONIC TECHNOLOGIES CO., LTD RBA5104 Preliminary LINEAR INTEGRATED CIRCUIT FAN REMOTE CONTROL ENCODER 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 ORDERING INFORMATION Ordering Number Lead Free Halogen Free RBA5104L-D16-T RBA5104G-D16-T Note: xx: Output Voltage, refer to Marking Information.
