CD74HCT7046AEG4

Overview

The CD74HCT7046AEG4 is a Phase Locked Loop (PLL) integrated circuit manufactured by Texas Instruments. It operates on Silicon technology within the 74HCT logic family, featuring a single circuit configuration housed in a 16-SOIC package. The device supports a supply voltage range of 4.5 V to 5.5 V and functions at frequencies up to 38 MHz. It is designed for surface-mount installation and maintains reliable operation across an extended temperature range from -55°C to +125°C.

Feature Summary

• Integrates a Phase-Locked Loop with Voltage-Controlled Oscillator
• Compatible with standard HCT logic input levels
• Supports wide industrial operating temperatures

Applications

• Frequency synthesis circuits
• Clock recovery systems
• FM demodulation applications

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status during procurement. Confirm the 16-SOIC package dimensions match the target PCB footprint. Ensure the 4.5V to 5.5V supply requirement aligns with the system design constraints before ordering.

Selection Notes

Select this component when HCT logic compatibility is required for interfacing with other digital circuits. The SOIC-16 package is suitable for automated surface-mount assembly processes. Verify that the 38 MHz maximum frequency meets the application's bandwidth requirements.

Part Context

This part belongs to the CD74HCT7046A series of PLLs. The 'G4' suffix typically denotes environmental compliance features such as lead-free construction. It serves as a high-speed variant compared to standard HC series devices, offering improved noise margins for 5V logic systems.

Replacement Considerations

Direct replacements include CD74HCT7046AM or CD74HCT7046APWR. Verify pinout compatibility and electrical specifications before substituting.
