SAA3049A Datasheet | Philips Semiconductors

FEATURES - Decodes 64 remote control mands with a maximum of 32 subaddresses - Accepts RECS80 codes with pulse position modulation (SAA3004, SAA3007, SAA3008) or RC5 codes with bi-phase transmission (SAA3006, SAA3010) - Suitable for low voltage and low SAA3049A supply current applications - Adding circuitry for binary decoding allows a maximum of 2048 mands to be used, for example 1-of-16 decoder (HEF4515). ORDERING INFORMATION TYPE NUMBER SAA3049AP SAA3049AT PACKAGE NAME DIP20 SO20 DESCRIPTION plastic dual in-line package; 20 leads (300 mil) plastic small outline package; 20 leads; body width 7.5 mm GENERAL DESCRIPTION The main function of the SAA3049A is to check and convert the received coded data (RECS80/RC5) into latched binary outputs. The device address can be hard-wired for a particular address, allowing several devices in one location. Alternatively, received data with any address can be accepted; the received data and address are then outputs.
