Preliminary
PT2282
PT2282 is a programmable rolling code encoder IC utilizing CMOS Technology specially designed for
remote control applications. It has a maximum of 20 programmable Address Codes, 4 Data Bits, and 10
Rolling Code Bits. A total of 1,024 rolling code combinations and power saving feature are also provided.
PT2282 encodes the programmed codes into a coded waveform suitable for RF modulation. Pin assign-
ments and application circuit are optimized for easy PCB Layout and cost saving advantage. Housed in
either 8 pins or 16 pins DIP or SO Package, PT2282 also provides anti-scan features.
