Programmable Encoder IC

PT2240

DESCRIPTION

PT2240 is programmable encoder utilizing CMOS Technology specially designed for remote control

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.
