CD74HC7046AM96

Overview

The CD74HC7046AM96 is a high-speed CMOS phase-locked loop (PLL) integrated circuit manufactured by Texas Instruments. It integrates a voltage-controlled oscillator (VCO), a lock detector, and two phase comparators within a single package. The device operates on a single power supply ranging from 2 V to 6 V. It supports input frequencies up to 38 MHz and functions reliably across an extended temperature range of -55°C to +125°C. The component is housed in a 16-pin SSOP surface-mount package.

Feature Summary

• Integrates a wide-range voltage-controlled oscillator (VCO) capable of operation with external components.
• Includes a dedicated lock detector output for monitoring phase-lock status.
• Provides dual phase comparator options: Phase Comparator A for frequency synthesis and Phase Comparator B for digital PLL applications.

Applications

• Frequency synthesizers for communication systems
• Clock recovery circuits in data transmission
• Motor speed control loops

Procurement Notes

Verify the specific suffix '96' against the manufacturer's official documentation to confirm the SSOP-24 or similar tape-and-reel packaging configuration. Ensure that the ordering information matches the exact pinout and electrical specifications required for the design. Cross-reference the datasheet revision history to confirm compliance with current RoHS standards before finalizing procurement.

Selection Notes

Select this component when a complete PLL solution including VCO and lock detection is required in a compact form factor. The HC logic family ensures compatibility with standard 5V and 3.3V logic levels. Consider the operating temperature range and supply voltage limits during system design to ensure reliable performance under varying environmental conditions.

Part Context

This part belongs to the Texas Instruments CD74HC7046A series of high-speed CMOS logic devices. The series is designed for general-purpose PLL applications, offering a balance of performance and low power consumption. The AM96 variant specifically denotes the industrial temperature grade and the specific reel packaging format used for automated assembly processes.

Replacement Considerations

Compatible substitutes include the CD74HCT7046AM96 for HCT logic level compatibility and the CD74HC4046AM96 if only one phase comparator is needed. Verify pin-to-pin compatibility and electrical parameter alignment with the original datasheet before substitution.
