FEATURES
GENERAL DESCRIPTION
·
Decodes 64 remote control commands with a maximum
of 32 subaddresses
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.
·
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).

HANDLING
Inputs and outputs are protected against electrostatic charge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices (see “Handling MOS Devices”).
