This is a infrared Remote Control Decoder circuit. This circuit uses the SAA3049A which is used to check and convert the received coded data (RECS80/RC5) into latched binary outputs. We can uses several device in one location because the device address can be hard-wired for a particular address. The output of this device are the received data and address. Here is the circuit:
This device has several feature such as it is suitable for low SAA3049A and low voltage supply current applications, it can accept RC5 codes with bi-phase transmission (SAA3006, SAA3010) or RECS80 codes with pulse position modulation (SAA3004, SAA3007, SAA3008) and it can Decodes 64remote control commands with a maximum of 32 subaddresses. Besides that a maximum commands of this device is up to 2048 by adding circuitry for binary decoding, for example 1-of-16 decoder (HEF4515). [Source: NXP Application Note]
