| Princeton Technology Corp. Programmable Encoder IC Tel : 886-2-29162151 Fax: 886-2-29174598 URL: http://www.princeton.com.tw PT2241 DESCRIPTION PT2241 is a tri-state programmable encoder utilizing CMOS Technology specially designed for remote control applications. It encodes address and data codes into a coded waveform suitable for RF modulation and can provide up to 11 Address which may be designed by a one-time programmable process. PT2241 can support up to 4 Data Bits, thereby reducing inventory pressures. It is housed in 8 or 16-pin DIP or SO Package. The pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantage.
