DESCRIPTION
PT2240 is programmable encoder utilizing CMOS Technology specially designed for remote control applications. It has a maximum of 222 Address which may be designed by a one-time programmable process. It can support up to 8 Data Bits and is housed in 8 or 16-pin DIP or SOP. It encodes address and data codes into a coded waveform suitable for RF modulation. The pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantage. Furthermore, PT2240’s intrinsic feature of being able to support 2/3/4/6/8 data bits considerably reduces inventory pressures.
