It supports up to 20 or 24 bits of programmable address codes, 8 or 4 data bits and 16 bits programmable rolling code. A total of 65,536 rolling code combinations as well as power saving feature and low battery warn mode(except PT2283L) are also provided. PT2283 encodes the programmed codes into a coded waveform suitable for RF modulation. Pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantage. Housed in either 8 pins or 16 pins DIP or SOP package.
