Overview
SL3010 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.

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.
If no connection is present the system number will not be generated.
Activating two or more X-inputs, Z-inputs or Z-inputs and X-inputs at the same time is an illegal action and inhibits f...
