NT2174/2175/2184/2185 series KEELOQ Decoders IC
NT21XX series is the wireless remote control for the rolling code security system and the development, matching with Microchip's HCS series. Different manufacturers can be produced by different factory code, the same manufacturer of the different users have different serial numbers in order to introduce the remote control code to distinguish re-code problems.The remote control sends the same probability of duplication of code Keelog technology can guarantee 18 years under the non-repetition, in order to prevent code-breaking problems. For fixed code decoding chip capacity bottlenecks and data and easily decipher the disadvantage (for example: PT2272/MC145027/AX5327/VD5027 / SC41343), NT21XX series is the ideal upgrade IC, as easy as PT2272.
