The LM567 and LM567C are general purpose tone decoders designed to provide a saturated transistor switch to ground when an input signal is present within the passband.
The circuit consists of an I and Q detector driven by a voltage controlled oscillator which determines the center frequency the decoder. External components are used to independently set center frequency, bandwidth and output delay.
