MAX7455UUP+T

Video Processing Overview

The MAX7455UUP+T is a video on-screen display (OSD) controller manufactured by Analog Devices Inc./Maxim Integrated. It integrates a full OSD engine with an internal 20-pin TSSOP package, designed for consumer circuit applications using BICMOS technology. The device functions as a video filter and buffer, enabling the overlay of text and graphics onto composite video signals. It supports standard NTSC and PAL formats, providing a cost-effective solution for adding user interface elements to video systems without requiring external microcontrollers for basic display tasks.

Video Processing Feature Summary

• Integrates a complete on-screen display engine within a single chip
• Supports direct overlay of alphanumeric characters and graphics onto video streams
• Compatible with standard NTSC and PAL video signal formats

Video Processing Applications

• Consumer electronics video interfaces
• Set-top box menu overlays
• Video monitoring systems

Video Processing Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check current lifecycle status as older Maxim parts may be discontinued or subject to limited availability. Ensure compatibility with existing PCB footprint and voltage levels before procurement.

Video Processing Selection Notes

Select this component when a dedicated, low-cost OSD solution is required for composite video applications. It is suitable for designs needing integrated character generation without complex external processing. Consider pin count and package size constraints, as it utilizes a 20-TSSOP form factor. Evaluate power supply requirements against system voltage rails.
