CD74HC7046AE

Overview

The CD74HC7046AE is a Phase Locked Loop (PLL) integrated circuit manufactured by Harris Corporation. It utilizes high-speed CMOS technology and operates within a supply voltage range of 2V to 6V, with a nominal voltage of 5V. The device supports a maximum frequency of 38MHz and functions across an extended temperature range from -55°C to 125°C. It is housed in a 16-pin Dual In-line Package (DIP) designed for through-hole mounting.

Feature Summary

• Integrates a complete phase-locked loop system including a voltage-controlled oscillator and phase detector.

Applications

• High-frequency tracking circuits for sensor heating power.

Procurement Notes

Verify the manufacturer designation as Harris Corporation on the component marking. Confirm the package type is 16-DIP and the operating temperature range covers -55°C to 125°C. Ensure the part number suffix matches 'AE' for the specific variant described in official documentation.

Selection Notes

Select this component when a single-channel PLL with high-speed CMOS performance is required. Verify that the application demands a supply voltage compatible with the 2V to 6V range and that the operational environment falls within the specified industrial or military temperature limits.
