74HCT4046N** is a high-speed CMOS phase-locked loop (PLL) IC manufactured by **Philips (PHI)**.

The 74HCT4046N is a high-speed CMOS phase-locked loop (PLL) IC manufactured by Philips (PHI).

Specifications:

  • Supply Voltage (VCC): 4.5V to 5.5V
  • Operating Temperature Range: -40°C to +85°C
  • Low Power Consumption: CMOS technology ensures low power dissipation
  • Phase Comparators: Includes three phase comparators (PC1, PC2, PC3)
  • VCO (Voltage-Controlled Oscillator) Range: Adjustable via external components
  • Input Frequency (VCO): Up to 18 MHz (typical)
  • Output Drive Capability: 4 mA at 4.5V
  • Package Type: DIP-16 (Dual In-line Package)

Descriptions:

The 74HCT4046N is a PLL IC that integrates a voltage-controlled oscillator (VCO) and multiple phase comparators. It is widely used in frequency synthesis, demodulation, clock recovery, and FM modulation/demodulation applications.

Features:

  • HCMOS Technology: Ensures compatibility with TTL levels
  • Three Phase Comparators:
  • PC1 (Exclusive-OR): Provides a digital phase comparison
  • PC2 (Edge-Triggered): Offers better noise immunity
  • PC3 (RS Flip-Flop): Used for frequency multiplication
  • Built-in VCO: Frequency determined by external resistor and capacitor
  • High Noise Immunity: Suitable for industrial environments
  • Wide Operating Voltage Range: Ensures stable performance

This IC is commonly used in communication systems, frequency synthesizers, and signal conditioning circuits.
