| 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.

A Subsidiary of Realtek Group Absolute Maximum Ratings DC Supply Voltage......................................2V to 5V Input/Output Voltag.......VDD 0.2V to GND 0.2V Operating temperature.....................-10 C to 60 C Storage Temperature.....................-25 C to 125 C Comments* Never allow a stress to exceed the values listed under "Absolute Maximun Ratings", otherwise the device would suffer from a permanent damage. Nor is a stress at the listed value be allowed to persist over a period, since an extended exposure to the absolute maximum rating condition may also affect the reliability of the device, if not causing a damage thereof.
