PT2240
DESCRIPTION
PT2240 is programmable encoder utilizing CMOS Technology specially designed for remote control
applications. It has a maximum of 222 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 SOP. 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.
