PT2240

DESCRIPTION

PT2240B is encoder utilizing CMOS Technology specially designed for remote control applications. It

has 220 Address. It can support up to 4 Data Bits and is housed in 8 pin SOP 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.
