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. It is specifically
designed to be used in RF keyless
remote control applications and is
available in 18pin SO and DIL
packages.
