NE567N is a tone decoder/phase-locked loop (PLL) IC manufactured by **Philips (PHI)**.

The NE567N is a tone decoder/phase-locked loop (PLL) IC manufactured by Philips (PHI).

Specifications:

  • Supply Voltage Range: 4.75V to 9V
  • Operating Frequency Range: 0.01Hz to 500kHz
  • Low Standby Current: 3mA (typical)
  • High Output Current Capability: Up to 100mA
  • Bandwidth Adjustable: Via external resistor and capacitor
  • Built-in Voltage Regulator: Ensures stable operation
  • Temperature Range: 0°C to +70°C

Descriptions:

The NE567N is designed to detect a specific frequency within a given bandwidth. It includes an internal PLL with an amplifier, phase detector, and voltage-controlled oscillator (VCO). When the input signal matches the set frequency, the output activates.

Features:

  • Frequency Lock Detection: Reliable tone decoding
  • Adjustable Bandwidth: Customizable via external components
  • High Noise Immunity: Rejects unwanted signals
  • Open-Collector Output: Compatible with various logic levels
  • Wide Operating Voltage: Suitable for multiple applications

This IC is commonly used in tone detection, remote control systems, and frequency-selective applications.
