Shown herearcseveral possible interface circuits that can be used with the remote-control transmitter. The one in A illustrates a typical FM stereo MUX decoder with a load connected directly to the open-collector output of aTA7343PLL. The circuit illustrates an optoisolator- coupler output driving a 12-V relay coil via a general-purpose transistor. C shows the gate of an N-channel power MOSFET connected to the output of a4N33.The final circuit, D, is a toggle flip-flop that allows push-on/push-off control.
