CD74HC4046AM96G4

Overview

The CD74HC4046AM96G4 is a high-speed CMOS logic phase-locked loop (PLL) integrated circuit manufactured by Texas Instruments. It features an integrated voltage-controlled oscillator (VCO) and three distinct phase comparers, designated as PC1, PC2, and PC3. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum frequency of 38 MHz. It is housed in a 16-pin SOIC package with a width of 3.90 mm and functions reliably across an extended temperature range from -55°C to +125°C.

Feature Summary

• Integrates a linear voltage-controlled oscillator (VCO) utilizing linear operational amplifier technology for improved linearity.
• Includes three selectable phase comparers (PC1, PC2, PC3) to accommodate various loop filter requirements.
• Features self-biasing input circuits that maintain small voltage signals within the linear region of the input amplifier.

Applications

• Frequency synthesis systems
• Clock recovery circuits
• Motor speed control applications

Procurement Notes

Verify the specific suffix G4 indicates compliance with RoHS directives and lead-free manufacturing standards. Confirm the AM96 designation corresponds to the 16-SOIC package variant. Ensure the component matches the required operating temperature range and voltage specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when a single-chip PLL solution with multiple phase comparison options is required. The HC series offers higher speed performance compared to legacy CD4046B devices while maintaining pin compatibility. Consider the TSSOP or SOIC package formats for surface-mount assembly constraints and thermal management requirements.

Part Context

This part belongs to the Texas Instruments CD74HC4046A family of high-speed CMOS logic devices. It serves as a direct replacement for older CD4046B designs, offering enhanced switching speeds and lower power consumption. The family is widely utilized in communication systems requiring stable frequency generation and signal synchronization.

Replacement Considerations

The CD74HC4046AME4 is a verified equivalent part number within the same product family. Both variants share identical electrical characteristics and functional definitions. Verify package dimensions and pinout alignment during physical integration to ensure mechanical compatibility.
