MAX7447EUD+T

Overview

The MAX7447EUD+T is a four-channel active low-pass filter and buffer IC designed for video signal processing. It integrates four independent filters with a cutoff frequency of 27 MHz, optimized for NTSC, PAL, and interlaced SDTV video signals. The device provides asynchronous composite video (CVBS) input and supports S-Video applications. Packaged in a 14-pin TSSOP, it ensures high signal integrity for consumer electronics.

Feature Summary

• Integrates four independent active low-pass filters within a single package
• Provides buffering capabilities for S-Video and CVBS signal paths
• Filter response characteristics are specifically tuned for standard definition television formats

Applications

• S-Video signal processing circuits
• Composite video (CVBS) filtering stages
• NTSC and PAL decoder output conditioning
• Interlaced SDTV video signal chains

Procurement Notes

Verify the specific suffix EUD against the official Analog Devices datasheet to confirm the package type and temperature range. Ensure the +T designation matches the required reel quantity and tape specifications for your assembly line. Cross-reference the manufacturer part number with the current product status page to confirm availability and lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when designing video signal paths requiring integrated filtering and buffering for standard definition formats. The 27 MHz cutoff frequency aligns with typical bandwidth requirements for NTSC and PAL signals. Consider the 14-TSSOP package constraints for PCB layout and thermal management in dense consumer electronic designs.

Part Context

This component belongs to the Maxim Integrated video interface filter family, now under Analog Devices. It addresses the need for compact, multi-channel signal conditioning in portable and stationary video devices. The integration of buffers and filters reduces component count compared to discrete solutions.

Replacement Considerations

Consult the official Analog Devices replacement matrix for verified substitutes. Generic video filters may not match the specific 27 MHz response or channel configuration.
