TECHNICAL DATA INA3010 INFRARED REMOTE CONTROL TRANSMITTER RC-5 The INA3010 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.
