ML6428CS3

Video Processing Overview

The ML6428CS3 is a video interface integrated circuit manufactured by Fairchild Semiconductor, packaged in an 8-SOIC (0.154 inch width) surface-mount housing. It functions as a dual Y/C fourth-order Butterworth low-pass time filter optimized for minimum overshoot and flat group delay. The device operates within a supply voltage range of 4.5V to 5.5V and supports NTSC and PAL video standards. Designed for consumer applications, it integrates driver and filtering capabilities into a single component.

Video Processing Feature Summary

• Integrated video driver and filter functionality
• Supports NTSC and PAL standard video formats

Video Processing Applications

• Consumer video equipment
• Video interface circuits
• NTSC/PAL signal processing systems

Video Processing Procurement Notes

Verify the manufacturer origin, as this part was originally produced by Fairchild Semiconductor before its semiconductor division became onsemi. Confirm the package type is 8-SOIC with the specified 0.154-inch width. Check for obsolescence status, as distribution channels may list this component as discontinued or available only through surplus suppliers. Ensure compatibility with 4.5V to 5.5V power supplies.

Video Processing Selection Notes

Select this component when a dedicated video filter with integrated driving capability is required for NTSC or PAL signals. The Butterworth response ensures minimal overshoot, which is critical for maintaining video signal integrity. Verify that the 8-SOIC package fits the PCB layout constraints and that the operating voltage aligns with the system's 5V logic levels.

Video Processing Part Context

The ML6428 belongs to a family of video processing ICs designed for analog video signal conditioning. This specific model combines filtering and driving functions to simplify circuit design in consumer electronics. It addresses the need for precise frequency response in composite video paths without requiring external passive components for basic filtering stages.
