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.

FEATURES

• Decodes 64 remote control commands 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 commands to be used, for example 1-of-16 decoder (HEF4515).
