Overview
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.
0~4.
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 Package DIP-16 Packing Tube RBA5104G-D16-T  MARKING (1)Packing Type (2)Package Type (3)Green Package (1) T: Tube (2) D16: DIP-16 (3) G: Halogen Free and Lead Free, L: Lead Free www.
