SC6921&SC6922 (ꢀꢁꢂꢃꢄS&CIC0328)

REMOTE CONTROL TRANSMITTER

General Description:

SC6921 and SC6922 are high performance remote control transmitter COMS IC, it is specially designed for use on infrared

remote control applications. The custom codes (Max.) of SC6921 and SC6922 are available by setting external diodes and resistors.

The transmission code consists of “leader pulse “ ꢅ”16 bits custom code “and” 16 bits data code”.

Feature Description:
