MAX7456EUI+T

The MAX7456EUI+T by Analog Devices / Maxim Integrated is a single-channel monochrome on-screen display (OSD) generator designed to reduce system cost by integrating video driver, sync separator, video switch, and EEPROM functionalities. This device is compatible with both NTSC and PAL standards, offering 256 user-programmable characters or pictographs stored in its integrated EEPROM.

Key features include a 12 x 18 pixel character size, blinking and inverse character attributes, selectable brightness by row, and the ability to display up to 16 rows by 30 characters. It also incorporates sag compensation on the video-driver output and provides LOS, VSYNC, HSYNC, and clock outputs. The MAX7456EUI+T utilizes an SPI-compatible serial interface for in-circuit reprogramming.

This OSD generator is suitable for applications such as security switching systems, security cameras, industrial applications, in-cabin entertainment, and consumer electronics. It operates within a voltage range of 4.75V to 5.25V and is housed in a 28-pin TSSOP-EP package, designed for surface mounting.

The device is specified for an extended operating temperature range of -40°C to +85°C. It comes preloaded with a character set and can be reprogrammed as needed. The MAX7456EUI+T is a versatile component for adding graphical information overlays to video signals.
