CD54HC7046AF

Overview

The CD54HC7046AF is a high-speed CMOS Phase Locked Loop (PLL) integrated circuit manufactured by Harris Corporation. It operates within a supply voltage range of 2V to 6V and supports a maximum frequency of 38MHz. The device is designed for automotive temperature applications, functioning reliably between -55°C and 125°C. It features a single PLL circuit in an uncased chip package with no leads, utilizing CMOS technology for low power consumption and high noise immunity.

Feature Summary

• High-speed CMOS technology ensures fast switching speeds and low power dissipation.
• Automotive-grade temperature rating allows operation in extreme environmental conditions.
• Single-phase locked loop architecture provides compact signal processing capability.

Applications

• Frequency synthesis in communication systems
• Clock generation for digital circuits
• Motor speed control applications

Procurement Notes

Verify the specific suffix 'AF' against official Harris documentation to confirm the exact die configuration and automotive qualification status. Ensure compatibility with surface-mount assembly processes due to the uncased chip form factor. Cross-reference with current manufacturer datasheets to validate electrical characteristics and thermal performance specifications before integration.

Selection Notes

Select this component when a robust, automotive-rated PLL is required for harsh environments. The wide operating temperature range makes it suitable for under-hood or industrial applications. Consider the uncased package type for custom substrate mounting solutions where standard packages are unsuitable.

Part Context

This part belongs to the 54HC series of high-speed CMOS logic devices produced by Harris Corporation. The 54-series designation typically indicates military or automotive grade reliability standards compared to the commercial 74-series equivalents. It represents a specialized phase-locked loop solution within the broader family of CMOS timing and control ICs.

Replacement Considerations
