MAX7432AEUD+

Overview

The MAX7432AEUD+ is a high-performance, low-cost video reconstruction filter and buffer designed for standard definition digital TV (SDTV) applications. It operates on a single +5V supply and features a 6th-order lowpass filter optimized for NTSC, PAL, and SDTV signals. The device includes a single-pin bus interface for digital control of channel selection, high-frequency boost, bypass modes, and output disable. It is housed in a 14-pin TSSOP package and is suitable for driving two 150Ω video loads.

Feature Summary

• Single-pin bus interface for digital configuration
• Sixth-order lowpass filter design
• Configurable high-frequency boost levels
• Integrated input multiplexer

Applications

• NTSC and PAL video signal processing
• Standard definition digital TV reconstruction
• S-Video (Y/C) applications
• Composite video (CVBS) outputs

Procurement Notes

Verify the authenticity of the component by checking for the correct manufacturer marking and date code. Ensure the package matches the 14-pin TSSOP specification. Confirm that the suffix indicates the lead-free and RoHS-compliant variant as specified in the official documentation.

Selection Notes

Select this component when a dedicated video reconstruction filter is required for SDTV systems. It serves as a replacement for discrete filter solutions. Consider the single-supply requirement and the specific need for digital control via the single-pin bus interface when designing the system architecture.

Part Context

This part belongs to the MAX7428/MAX7430/MAX7432A family of video filters. The MAX7432A variant specifically targets RGB and YPbPr applications with its dual-filter structure, distinguishing it from the single-channel MAX7428 and S-Video optimized MAX7430 within the same product line.

Replacement Considerations

The MAX7432AEUD+ may replace discrete filter and buffer solutions in existing designs. Verify pin compatibility and electrical specifications against the original components before substitution.
