INFRARED REMOTE CONTROL TRANSMITTER RC-5
The SL3010 is intended as a general purpose (RC-5) infrared remote control system for use where a low
voltage supply and a large debounce time are expected. The device can generate 2048 different commands and utilizes a keyboard with a single pole switch for each key. The command are arranged so that 32 systems can be addressed, each system containing 64 different commands. The keyboard interconnection is illustrated by Fig.1.
