KRX416
Code-hopping decoder with 4 outputs
Key-code Receiver 416 is a single IC solution for decrypting and decoding Radiometrix code-hopping transmitters. The device will retain the identities of up to 16 code-hopping transmitters, even when the power supply is removed. Specifically designed to be used in RF keyless remote control applications. Available in 18pin SO and DIL packages.
