The HCSXXX Decoder family operates over a wide voltage range of 3.0 volts to 6.0 volts. The decoders employ automatic bit-rate detection, which allows them to compensate for wide variations in transmitter data rate. The decoders contain sophisticated error checking algorithms to ensure only valid codes are accepted. The KEELOQ family of code hopping devices provide a simple yet highly secure solution for remote control locking devices, house keys, garage door openers and home security systems. The key is a proprietary, non-linear encryption algorithm that creates a unique transmission on every use, rendering code capture, scanning and resend schemes useless.
