  • TT-16 SWEET 16 TONE DECODER
    Operates great through phone lines, radios or scanners.
    The TT16 provides a design platform you can use your imagination to build on. The SWEET 16 TONE DECODER detects ( DTMF) “Dual Tone Multi-Frequency” data (those sounds you hear when pushing buttons on your phone), and when each individual button is pressed
    it sends a unique voltage to the electronics on the printed
    circuit board which activates a circuit on or off. There are 16 different touch tones, 12 of which are on a normal phone;
    special key pads have 4 additional buttons (A, B, C, D,). 
    This decoder gives an output voltage for all 16 touch tones. 
    The Sweet 16 Tone Decoder has on the printed circuit board one
    (1) relay and driver circuit. If you want to use all 16 you can build
    your own board with 16 relays and driver circuits on it, or to get
    fancier use a flip-flop IC to achieve a “toggle” effect (push ON, push
    OFF), or a 555-timer to provide a timing effect (on for 5 minutes, then off) - the choices are almost unlimited. Any one output may be connected to the onboard relay circuit. 
    PC Board Size: 2.25” x 2.75”
