Description and Introduction

Low Power Tone Decoder The LMC567CN is a low-power tone decoder manufactured by National Semiconductor (NSC). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage Range:** 4.75V to 9V  
- **Operating Current:** 3mA (typical at 5V)  
- **Frequency Range:** 0.01Hz to 500kHz  
- **Input Sensitivity:** 20mV (minimum detectable signal)  
- **Output Sink Current:** 50mA (maximum)  
- **Package:** 8-Pin DIP (Dual In-line Package)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
- The LMC567CN is a CMOS tone decoder designed to detect a specific frequency within a given bandwidth.  
- It includes an internal oscillator, phase detector, and output driver for relay or logic interfacing.  
- Commonly used in applications such as tone detection, frequency-shift keying (FSK) demodulation, and remote control systems.  

### **Features:**  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Adjustable Bandwidth:** Allows precise frequency detection tuning.  
- **High Noise Immunity:** Minimizes false triggering.  
- **On-Chip Voltage Regulator:** Ensures stable operation over supply variations.  
- **TTL/CMOS-Compatible Output:** Simplifies interfacing with digital circuits.  

This information is based solely on the manufacturer's datasheet. For detailed application notes, refer to the official NSC documentation.
