MAX7456EUI+T

Product Summary

The MAX7456EUI+T is a single-channel monochrome on-screen display (OSD) generator. It lowers system cost by elimi- nating the need for an external video driver, sync separator, video switch, and EEPROM. The MAX7456EUI+T serves all national and international markets with 256 user-pro- grammable characters in NTSC and PAL standards. The MAX7456EUI+T easily displays information such as company logo, custom graphics, time, and date with arbitrary characters and sizes. The MAX7456EUI+T is preloaded with 256 characters and pictographs and can be reprogrammed in-circuit using the SPI port. The applications are (1)Security Switching Systems; (2)Security Cameras; (3)Industrial Applications; (4)In-Cabin Entertainment; (5)Consumer Electronics.
