PT2240B
Encoder IC
DESCRIPTION
PT2240B is encoder utilizing CMOS Technology
specially designed for remote control applications. It
has 2
20
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.
