DESCRIPTION
The STV3012 is a general purpose infrared remote
control transmitter system for low voltage supply
applications. It is able to generate a total number
of 448 commands which are divided into 7 sub-sys-
tem groups with 64 commands each. The sub-sys-
tem code may be selected by a press button, a
slider switch or hard wired. Two different timing and
data format modes are available.
