PT2240B

Encoder IC

Princeton Technology 

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.
