Encoder IC
Description
PT2240B
PT2240B is encoder utilizing CMOS Technology specially designed for remote control applications. It has
20 Address. It can support up to 4 Data Bits and is housed in 8 pin 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, PT2240B’s intrinsic feature
of being able to support 4 data bits considerably reduces inventory pressures.
