System Logic Semiconductor SL3010DW
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.| Part No. | SL3010DW |

Keyboard operation Every connection of one X-input and one DR-output will be recognized as a legal key operation and will cause the device to generate the corresponding code. The same applies to every connection of one Z-input to one DRoutput with the proviso that SSM must be LOW. When SSM is HIGH a wired connection must exist between a Zinput and DR-output.
