SAA3049A is an infrared remote control decoder produced by Philips Semiconductors. The product supports 64 remote control commands with a maximum of 32 subaddresses. It supports RECS80 codes with pulse position modulation (SAA3004, SAA3007, SAA3008) or RC5 codes with bi-phase transmission (SAA3006, SAA3010). It is suitable for low voltage and low SAA3049A supply current applications.
The Philips SAA3049A is an integrated circuit designed to decode 64 remote control commands with a maximum of 32 subaddresses. It accepts inputs from various transmitters using pulse position modulation (RECS80) or bi-phase transmission (RC5). The device converts received coded data into latched binary outputs, allowing the address to be hard-wired for specific applications or passed through as output data.
The component is suitable for low voltage and low supply current applications. It features a system diagram compatible with transmitters such as SAA3004, SAA3007, SAA3008, SAA3006, and SAA3010. The datasheet provides detailed pinning information, limiting values for operating conditions, electrical characteristics, and application circuit examples including reset circuits and mode selection configurations.
