Texas Instruments IC TELECOM INTERFACE 8SOIC LM567CM/NOPB

The LM567CM/NOPB is a monolithic phase-locked loop (PLL) tone decoder IC in an SOP package, designed for general-purpose frequency detection and tone decoding applications. It operates with a supply voltage up to 9V and has a temperature range of -40°C to +85°C. This device locks onto input signals and provides a digital output when the signal matches a pre-set frequency, making it suitable for various control and security systems.
