GENERAL DESCRIPTION

The SM5021A/B is a high performance

infrared remote control encoder utilizing

CMOS technology. Mode A is a signal-key

control and mode B is a multi-key control

during data transmission, supports eight data

key inputs and a LED output to indicate the

status during transmission.

Auto power off function when key is not

pressed to save power, custom codes to

distinguish different products. SM5021

encoder is paired with SM5032 decoder for

more data control applications.
