■ GENERAL DESCRIPTION
The NJM2129 is a remote-control interface for television, VCR, receiver, and others.
The signal flow of IN1 to OUT1 and IN2 to OUT2 is a first priority. When no signal is input from the IN2, a signal which is input from the IN1 is output to the OUT2 through the OUT1. Also when no signal is input from IN1 and IN2, a signal which is input from the OUT1 is output to the OUT2.
An internal regulator can operate a LED.
