FMS6400CSX

Overview

The FMS6400CSX is a video driver integrated circuit manufactured by onsemi, formerly Fairchild Semiconductor. It is designed for PAL standard video signal processing within consumer electronics applications. The device operates on a single supply voltage ranging from 4.75V to 5.25V and draws a typical operating current of 60mA. It supports an ambient operating temperature range from 0°C to +70°C. The component is housed in an 8-SOIC surface-mount package with a width of 3.90mm. It features AC-coupled inputs and outputs, allowing compatibility with various video source configurations without requiring external coupling capacitors for the output stage.

Feature Summary

• Integrates video filtering and driving capabilities to replace discrete passive LC filter components
• Supports both AC-coupled and DC-coupled input signal connections
• Provides AC-coupled output stages suitable for direct connection to display loads
• Designed for low-cost implementation in consumer video signal conditioning circuits

Applications

• Consumer video signal conditioning
• PAL standard video driver circuits
• Replacement for discrete LC filter networks in video paths

Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels due to discontinued status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Check for obsolescence notices or last-time buy availability if sourcing for new production. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines to prevent package damage prior to assembly.

Selection Notes

Select this component when designing PAL-compatible video interfaces requiring integrated filtering and driving functions. Verify that the 8-SOIC package footprint aligns with the target PCB layout constraints. Ensure the system power supply remains stable within the 4.75V to 5.25V operational window. Consider thermal management requirements given the 0°C to +70°C operating range for enclosed consumer enclosures.

Part Context

This part belongs to the FMS6400 series of video interface devices originally developed by Fairchild Semiconductor, now under onsemi. The series targets cost-sensitive consumer electronics markets where space efficiency and reduced bill-of-materials complexity are critical. The CSX suffix typically denotes a tape-and-reel packaging variant optimized for automated surface-mount assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component status is listed as obsolete. Designers should consult official manufacturer lifecycle notifications for potential end-of-life alternatives or cross-reference compatible video driver ICs with matching SOIC-8 pinouts and electrical specifications.
