www.DataSheet4U.com RTS715-3 M-SQUARE Technologies Corp. A Subsidiary of Realtek Group INFRARED/R.F. TRANSMITTER Features - Wide operating voltage range: 2.4V to 5.0V Low Stand-by current(except RF mode) Operating frequency 1.2 MHz,crystal/RC oscillation for system operation (by change of application circuit) RTS715-3 can combine with RTS510B and RTS511B to become a three-wind mode, three-wind grade and two-timing function infrared remote controller for fans Suitable for infrared or radio frequency remote controller system Two choices of input function (Eight or one channel) Auto Power-OFF after a all keys released Provide two transmissive interface(RF and IR)for different application. Support 38KHz narrow band IR receiver . General Description The RTS715-3 is a CMOS LSI designed to function as transmitters. The RTS715-3 provides seven functions and can combine with RTS510B and RTS511B. As a infrared remote controller, each data input has a corresponding output signal code, and for the convenience, users can define a decoder to decode the signal to meet different applications.
