... LM567/LM567C Tone Decoder General Description 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 and Q detector driven by a voltage controlled oscillator which determines the center frequency of the decoder ...

... Note 2: The maximum junction temperature of the LM567 and LM567C is 150˚C. For operating at elevated temperatures, devices in the TO-5 package must be derated based on a thermal resistance of 150˚C/W, junction to ambient or 45˚C/W, junction to case. For the DIP the device must be derated based on a thermal resistance of 110˚ ...
