CD74HC4046AE

Overview

The CD74HC4046AE is a 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 housed in a 16-DIP package with a width of 0.300 inches (7.62mm). It functions as a single-circuit PLL designed for clock generation and frequency synthesis applications. The component is rated for an operating temperature range from -55°C to 125°C. Input and output logic levels are specified as CMOS. The part status is listed as discontinued.

Feature Summary

• Integrates a high-speed CMOS phase-locked loop architecture
• Supports operation across extended industrial temperature ranges
• Compatible with standard DIP mounting configurations

Applications

• Clock generation circuits
• Frequency synthesis systems
• Phase-locked loop implementations

Procurement Notes

Verify the current availability status, as the CD74HC4046AE is classified as a discontinued product. Confirm that the specific manufacturer designation aligns with project requirements, noting potential variations between original Harris Corporation production and subsequent distributor inventory sources. Ensure compliance with relevant export control classifications such as EAR99 before finalizing acquisition plans.

Selection Notes

Select this component when a legacy 16-pin DIP form factor is required for through-hole assembly. Verify that the 38MHz maximum frequency specification meets the system's timing constraints. Consider the 2V to 6V supply voltage range compatibility with existing power rails. Evaluate the -55°C to 125°C operating temperature range against environmental conditions.

Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It serves as a specialized variant within the broader 74HC family, focusing specifically on phase-locked loop functionality rather than general-purpose logic gates. The device maintains pin compatibility with related legacy components while offering improved speed characteristics typical of the HC technology node.
