Programmable Encoder IC
PT2240
Description
PT2240 is programmable encoder utilizing CMOS Technology specially designed for remote
control applications. It has a maximum of 22 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 SO
Package. 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.
