PT2241
DESCRIPTION
PT2241 is a tri-state programmable encoder utilizing CMOS Technology specially designed for remote
control applications. It encodes address and data codes into a coded waveform suitable for RF modula-
tion and can provide up to 11 Address which may be designed by a one-time programmable process.
PT2241 can support up to 4 Data Bits, thereby reducing inventory pressures. It is housed in 8 or 16-pin
DIP or SO Package. The pin assignments and application circuit are optimized for easy PCB Layout
and cost saving advantage.
