Texas Instruments IC TELECOM INTERFACE 8SOIC LM567CMX/NOPB

The LM567CMX/NOPB is a variant of the LM567 integrated circuit, which is a versatile phase-locked loop (PLL) tone decoder. This device, manufactured by Texas Instruments or compatible suppliers, is primarily used for frequency detection and filtering applications within a specified frequency range. It ensures that the internal oscillator locks onto an input signal when fed to pin 3 with an amplitude ≥ 25mV and a frequency within its bandwidth. The 'CMX' indicates a commercial temperature range and 'NOPB' signifies No Pb, denoting the part is RoHS compliant, i.e., lead-free.
