See the preview image and the PDF file for more information.
SCT2260 is a low-power general-purpose coding circuit manufactured by CMOS process, A circuit has a user can be flexible to change the address code and data code for the composition, electricity Road has a power saving mode that can be used for radio remote control / infrared emission, with PT2260 compatible.
A0 ~ Ax : input address pin for address encoding, can be set to “0”, “1”, “f” (floating),
D0 ~ Dx : input data input, there is a “1” that is encoded, the internal pull down;
Vcc : input power supply positive terminal (+) input;
Vss : input power supply negative terminal (-) input terminal;
OSC : input single-ended resistor oscillator input, and power supply connected to determine the oscillation frequency;
Dout : output code output (often low); […]
